Controlling Catalytic Reactions: Recent Report Amit Kumar Department of Biotechnology, Amity University, Noida, Uttar Pradesh, India

Catalysts play an important role in various chemical reactions. Their prime role is to speed up the reaction. Catalysts are required in very small amounts and are not consumed during the reaction. Today, catalysts are not only required by chemists to accelerate their chemical processes but they have become a crucial part of the industrial sector as well [1]. This is because use of catalyst in accelerating the reaction rate is also associated with the fact that a chemical compound can be synthesized more economically and cleanly. In a recent research led by a group of scientists at the University of Toronto, it is found that the catalytic reactions can be made more specific and faster. This research has been carried out by the Nobel Prize winner John Polanyi, a renowned chemist and his team [2]. They observed that altering the position of the molecule relative to the catalytic surface, renders the process of catalysis highly bond-specific.

The reaction mechanism becomes more selective when the alignment of the bonds in the molecules was closer to the rows of atoms in the catalyst. The team carried out carious experiments involving organic compound iodobenzene. Here, metallic copper was used as the catalyst. Reaction was initiated by movement of an electron that was transferred from the tip of the microscope towards iodobenzene [2]. This resulted in breaking of carbon-to-iodine bonds in the presence of the catalyst (copper). It was found that the reactivity of carbon-toiodine bonds got accelerated when those bonds were in the alignment to rows of atoms of the catalyst i.e., copper; than that when the carbon-to-iodine bonds were aligned across the copper rows. A 100-fold difference was observed in the reactivity of the reaction depending on the position of bonds in specific directions on the catalyst (Figure 1) [2].

Synthesis, Spectral and Magnetic Moment Studies of Mixed Ligand Complexes of Hydroxamic Acids with Potassium Hexathiocyanato Vanadium (II) Tetra Hydrate Ajay Agarwal*, Virendra Mishra, Babita Agarwal B.S.A. College of Engineering and Technology, Mathura, UP, India

ABSTRACT Preparation and characterization of several hydroxamic acids of 3,4,5-trimethoxy benzohydroxamic acids(TMBHA), N-phenyl–3,4,5-trimethoxy benzohydroxamic acid(PTMBHA), 3,4-dimethoxy benzohydroxamic acid(DMBHA) and N-phenyl-3,4dimethoxy benzohydroxamic acid(PDMBHA) were prepared and reacted with potassium hexathiocynato vandate (II) K4[V(NCS)6].3H2O tetra hydrate. The mixed ligand complexes of hydroxamic acids characterized with the help of repeated melting point identification, by I.R. studies, magnetic moment, molar conductance’s and by elemental analysis (C, H and N). The geometry of complexes were found to be octahedral. On the basis of these facts, the structure of the metal complexes found to be K2 [M(Lʹ)2(L1)2], K3[M(Lʹ)4(L2)], K2[M(Lʹ)2(L3)2] and K3[M(Lʹ)4(L4)]. Keywords: hydroxamic acids, potassium hexathiocynato vanadate (II) and mixed ligand complexes

INTRODUCTION Hydroxamic acids can form metal complexes with a wide range of metals.[1] Hydroxamic acids act as bidentate ligand coordinates as an O, O and O, N donor sites. Hydroxamic acids form typical octahedral complexes with transition metals. The mixed ligand complexes of hydroxamic acids acts as biological and biocidal activities,[2] hypotensive,[3] [4] anticancer, anti-malarial,[5] antituberculosis properties[6] antibiotic,[7] antibiotic antagonist,[8] tumor inhibitor,[9] antifungal agents,[10] pharmaceutical[11] and industrial applications.[12] The introduction of secondary coordinating group like thiocynate does not change the coordination behavior of coordination (O, O) as bridging bis-chelating ligand. Very scanty work has been done with V (II) metal with hydroxamic acids.[13–15] Hence, keeping the above facts in mind, we

thought it is worthwhile to isolate some new complexes of hydroxamic acids with V (II) and thiocynate group as bridging chelating ligand. The interaction of Vanadium and hydroxamic acids gained a special interest owing to their use as bioinorganic model compounds to study their enzymatic interactions.[16] Vanadium has been known as an essential nutritional element that is found in remarkably high concentrations in marine ascidians[17]; in certain mushrooms.[18] Much of the interest is due to insulin mimetic potential role of vanadium,[19–22] therefore new drugs of the vanadium complexes have been proposed to function as potent. Vanadium is physiologically important trace element effective in helping to increase insulin sensitivity. Essential nutritional requirement in higher animals,

Identifying Chemical Combination in Consumer Products – A Report Varun Singh Parmar* Department of Pharmacy, Baba Mast Nath University, Rohtak, Haryana, India

ABSTRACT Chemical are both helpful as well as harmful. When used cautiously under preset and standardized protocols, they carry out several chemical reactions and synthesis. However, many of the products synthesized using chemicals have harmful effects. Many of the everyday use products such as cosmetics, detergents, toothpaste, etc., are composed of chemicals about which we are not aware of. These have several harmful side-effects and long term health issues associated with them. In a recent study, emphasis was laid down to identify the prevalence of individual chemical ingredients in daily use consumer products. Keywords: chemical, harmful, synthesized product

BACKGROUND Chemicals are not only useful in chemical processes; they have some harmful effects also. Humans are exposed to a variety of industrially synthesized products everyday. These include the daily used items such as soaps, toothpaste, shampoos, lotions, creams, make-up materials, body spray, etc. these products contain dozens of chemicals which might not be useful or healthy and rather have associated health risks, either individually or in combination. In a recent research by professors at the University of Illinois School of Information Sciences, an approach was made to determine the prevalence of individual ingredients and their most likely combinations in consumer products [1]. Consumer chemical product implies to those materials that consist of a mixture of chemicals and/or brings about a chemical reaction when used by the consumer [2]. To identify the chemicals present in the daily used consumer products, the researchers used a web-scraping program.

This program could collect name of different products, categories and the several ingredient lists that were used in synthesis of the consumable products. The information and data was retrieved from the online portal of retail sites such as Drugstore.com. This database is now available with details of nearly 39,000 products and above 32,000 ingredient names. Once, the list of ingredients in consumer products was made, next step followed was to solve the problem of chemical synonymy i.e., the exercise of using various names for the same substance. This was important to have accurate counting while inserting the same product name multiple times. Professor Catherine Blake along with his doctoral student Henry Gabb identified 55 potential chemicals related with endocrinedisruption and asthma disorder using the techniques of gas chromatography-mass spectrometry analysis with the objective of determining the level of these chemicals in consumable products.

Successful Synthesis of Organic Molecules with Increased Conductivity and Durability Dayananda Singh Konjengbam* Department of Chemistry, Bundelkhand University, Jhansi, India

ABSTRACT Organic molecules are central to biological and chemical systems. Organic molecules are mainly composed of hydrogen and carbon. These constitute the building blocks for all living organism. Chemists and scientist are curious in synthesizing organic molecules that have increased conductivity and durability. Several techniques have been developed and modified to achieve this target. A novel method has been discussed for synthesis of organic molecules with enhanced conductivity and durability. Keywords: biological, organic, synthesis

BACKGROUND Organic molecules play central role in biological as well as chemical systems. Due to this, their synthesis draws much attention of the scientists from all over the world. Scientists have developed a vast range of methods to synthesize and develop several organic molecules having varying properties and utilization. Organic molecules comprised of single elements have been in synthesis from last several years. These molecules though good polymers are however not ideal charge conductors. Such molecules do not exhibit carriers through which electric charge can pass through. Due to this limitation, they have not been good electric conductors. To modify their property, molecules combined with other metals have been synthesized for use as conductors. This practice has been in exercise from last 50 years. Combination with different metals alters the inherent property of the original molecule enabling generation of charge carriers. This practice however had a major limitation with the stability and durability of the synthesized

molecule. Also, synthesizing pure organic molecules made of a single component requires high pressure of at least 1 giga pascal (GPa) in order to obtain conductive like metal. This is difficult as an ambient pressure was required all the time during synthesis process. It is always important to understand the structure and function relationship while synthesizing an organic molecule with required properties. Also, the control and regulation of the physical and chemical properties related to the targeted structure and function should be taken into consideration. Several properties that are needed to be considered include [1]:  Ionization potential  Electron affinity  Madelung energy  Coulomb energy  Density of state  Fermi level  Chemical potential  Bandwidth  Acidity and basicity  Transfer interaction, etc.

Synthesis and Characterization of Mixed Ligand Complexes of Hydroxamic Acids with Potassium Hexathiocyanato Chromium (III) Tetra-hydrate Ajay Agarwal*, Virendra Mishra, Satnam Arora B.S.A College of Engineering and Technology, Mathura, Uttar Pradesh, India ABSTRACT Some hydroxamic acids e.g. [L1= benzohydroxamic acids (BHA), L2= N-phenyl– benzohydroxamic acid (NPBHA), L3= pivaloyl benzohydroxamic acid (PHA) and L4=Nphenyl-pivaloyl benzohydroxamic acid (PPHA) prepared and reacted with L’=Potassium hexathiocynato chromium (III) tetra hydrate K3[Cr(SCN)6]4H2O. The mixed ligand complexes of hydroxamic acids characterized with the help of repeated melting point, by I.R. studies, magnetic moment, molar conductance and by elemental analysis(C,H and N). The stoichiometry of the complexes were found to be 1:2(M:L) molar ratio. The geometry of complexes was found to be octahedral. On the basis of these facts the structure of the metal complexes found to be K [M(L’)2(L1)2], K2[M(L’)4(L2)], K2[M(L’)4(L3)] and K[M(L’)2(L4)2]. Keywords: hydroxamic acids, mixed ligand complexes, potassium hexathiocynato chromium (III)

INTRODUCTION Hydroxamic acids are the versatile organic compounds possessing biological1 and biocidal activities2-7. It is now evident that these weak acids possess specific biological activities8, that are largely attributed to their complexing properties towards transition metals9-10, their complexing properties toward transitionmetal ions11, food additives12-13, antibiotic antagonists, tumor inhibitors14-15, show significant inhibition of HIV protease in vitro16, antifungal agents17,cell divisions factors, versatile analytical reagents18-19 and several of them have been used as anti-malarial drugs20-21 agents, anti-cancer, antifungal and antibacterial activity, toxilogical, pharmacological importance22 and their –NO releasing properties23-24. Hydroxamic acids have bivalent coordination mode i.e., through the oxygen of deprotonated hydroxamic acids and through carbonyl oxygen atom (O,O) As a result, they are powerful ligand for a

great number of metal ions25-26. The introduction of secondary coordinating group like thiocynate does not change the coordination behavior of coordination (O,O) as bridging bis-chelating ligand27-28. Very scanty work has been done with the Cr (III) metal with hydroxamic acids. The importance of chromium in mammalian metabolism has been studied greatly. Diet deficient in chromium develops a visible eye lesion, which causes opacity29, hence keeping the above facts in mind, we thought it is worthwhile to isolate some new complexes of hydroxamic acids with Cr (III) and thiocynate group as bridging chelating ligand. Chromium compounds enhanced the action of insulin30 outstanding activity is manifested by the chromium complexes extracted from the brewer’s yeast and pork kidney powder. These act as a co-factor in
