General procedure: DABCO (1.0 mol equiv) was added to a suspension of the sugar (10.0 g, 51.5 mmol) in Ac2O (1.2 mol equiv per OH group) and the mixture was stirred at rt. After completion of the reaction (TLC, eluent, EtOAc:n-Hex, 2:3) the mixture was poured onto crushed ice and was stirred for a few min when precipitation of the desired methyl 2,3,4,6-tetra-O-acetyl-γ-dglucopyranoside took place along with dissolution of DABCO in water (the latter indicated by TLC and viewing the spot in an iodine chamber). The product was isolated by filtration at the pump followed by washing with ice-cold water and drying. It was pure enough for direct further use. Yield, 18.3 g, 98percent. An analytically pure sample was obtained by recrystallization from 95percent ethanol.It may be noted that addition of DABCO and stirring lead to warming up of the reaction mixture. In reactions carried out on 10-20 g scale this is advantageous in that considerable rate enhancement can be obtained in such cases. However in reactions on a much larger scale (50-100 g and above) the addition of DABCO should preferably be carried out portion-wise to keep the reaction mixture from getting over heated.

2.4. General procedure for acylation reaction General procedure: A 25mL sealed tube containing a magnetic stir bar was charged with phenol/alcohol/amine (1mmol) and acetic anhydride (1.5mmol), nano γ-Fe2O3 (5molpercent, 8mg) as catalyst. The reaction mixture was kept for sonication in sonication bath at room temperature (28°C) for 1h. The ultrasonic bath (Labman Scientific Instruments, Model – LMUC 4) had a frequency of 33kHz and electric power rating of 100W. The reaction progress was monitored on thin-layer chromatography (TLC) and gas chromatography (PerkinElmer, GC Clarus 400) analysis. After completion of the reaction, the reaction mixture was diluted with ethyl acetate and catalyst was separated from reaction mixture by using a strong magnet. The separated catalyst was washed with distilled water and absolute ethanol several times then dried in oven and reused for further reaction. The reaction mixture was washed with saturated NaHCO3 solution (1×15mL) and the product was extracted with ethyl acetate (3×10mL) and dried over Na2SO4 and evaporated under vacuum. All the obtained products are well known in the literature and were confirmed by gas chromatography–mass spectrometry (Shimadzu GCMS-QP 2010) analysis by comparison with literature data.

In a typical experience, the reactor was loadedwith a mixture of 1 mmol of 2-phenylethanol (122 mg), 5 mmolof acetic acid (300 mg), 5 cm3of toluene and 100 mg of the cata-lyst. The mixture was stirred at 700 rpm. Samples were withdrawnfrom the organic phase at different intervals (1, 3, 5, 7, 10 and14 h). Each sample volume was approximately 10 mm3and wasdiluted with 2 cm3of acetonitrile. The concentration of substrateswas calculated with the corresponding areas, using a ShimadzuHP2010 gas chromatography instrument (Chromopack CP Sil 8 CB,30 m × 0.32 mm ID). A similar procedure was followed with theother studied alcohols and phenols.After 14 h of reaction, the solution was concentrated undervacuum, and the residue was purified by column chromatogra-phy employing silica gel as the stationary phase and a mixtureof hexane-ethyl acetate as the elution solvent. The reaction prod-ucts were identified by chromatographic comparison with standardsamples. The conversion was expressed as the ratio of moles ofproducts to moles of initial alcohol.

der vigorous stirring. The progress of the reaction was monitored by TLC (hexane/ethyl acetate=4/1). After the completion,the mixture was extracted with diethyl ether (3 × 15 mL).The combined organic layer was washed with aqueous of NaHCO3(3 × 15 mL) and water (3 × 15 mL), then dried over anhydrous MgSO4, filtered, and concentrated under vacuum to afford the crude product. The crude product was purified by column chromatography using hexane–ethyl acetate 4:1 (V/V) as eluent. The obtained product was identified by comparing TLC, 1H NMR and IR spectra data with authentic sample. The catalyst was recovered by washed with diethylether (3 × 10 mL), and then dried under vacuum at 80 °C over 8 h.Oxidant efficiency is determined by iodometric titration methods described in literature [25]. The results revealed that the amount of H2O2 present at the reaction endpoint was 2–3 mmol.

Conditions & References 3.5. Benzene oxidation in non-acidic media The lack of benzene oxidation in HTFA (see above) could resultfrom the failure of the Rh complexes to mediate benzene C– Hactivation in trifluoroacetic acid. We speculated that non-acidicsolvents might allow arene functionalization chemistry (Eq. (3)).A 0.5 molpercent solution of 7 or 11 in benzene with 100 equivalents ofcopper (II) acetate was heated to 150C and 180C for 4 h. Analysisby GC/MS revealed no benzene functionalization at 150C. How-ever, at 180C the production of biphenyl and a minor quantity ofPhOAc was observed when using Cu(OAc)2. Control experimentsat 180C without rhodium catalyst produced the same quantity ofphenyl acetate; however, no biphenyl was observed. The formationof PhOAc presumably is due to reaction with Cu(OAc)2. This wasconfirmed by running a control reaction in toluene and producingsignificantly more benzylic acetate than tolylacetate (see Support-ing information, Scheme S1). The production of biphenyl was alsoobserved with catalyst 4, 7, 11 and [Rh(-TFA)(2-C2H4)2]2in sim-ilar yields.

Its synthesis procedure is reported by Curran et al. [24]. General procedure for Fries rearrangement was done by adding FSG to aryl ester at the ambient temperatures. Before adding FSG to reaction mixture, aryl esters were obtained by in situ formation through the reaction of acyl chloride derivatives and phenol derivatives. Thus, to a 100ml round bottom flask stirring by a magnetic bar 10mmol of phenols was added and then, 10mmol of acyl chloride derivatives (for catechols 20mmol) was added dropwise and allowed to react at room temperature. After 30min, temperature was raised to remove HCl from reaction mixture. Then 1g of FSG was added to reaction mixture at ambient temperature. After 4h heating at appropriate temperature in oil bath, the reaction mixture was cooled to room temperature and washed with dichloromethane. The catalyst was separated by filtration. The solvent was removed by rotary evaporator and resulting mixture was separated by column chromatography (stationary phase: silica-gel, eluent:hexane:ethyl acetate) and purified by recrystallization. All isolated products successfully gave related spectral data of IR, NMR, and mass spectrometers. in neat (no solvent), Time= 0.5h, T= 20 °C Ghaffarzadeh, Mohammad; Ahmadi, Maryam; Journal of Fluorine Chemistry; vol. 160; (2014); p. 77 - 81 View in Reaxys

General procedure for the O-acetylation of alcohols using N-acetyl DBN*BPh4 (3a) General procedure: N-acetyl DBN*BPh4 (3a) (1.3 equiv, 0.65 mmol) was added to a carousel tube and purged with nitrogen. Dry MeCN (2 mL), the appropriate alcohol (1 equiv, 0.5 mmol) and DBN (1) (20 mol percent, 0.1 mmol) were added and the resulting solution heated at 80 °C for 16 h. After being cooled to room temperature, the mixture was filtered and concentrated under reduced pressure. The crude product was suspended in a minimum amount of hot CHCl3 and allowed to cool before filtering off the insoluble salts. The filtrate was washed with NH4Cl(aq) and brine before being dried over MgSO4, filtered, and concentrated under reduced pressure.
