3.3; 3.5:Example 3.1 General Procedures

General procedure: Example 3.1 General Procedures Example 3.1.1 Procedure (A) for Larger-Scale (0.5 Mmol) Oxidation of Aliphatic Alkenes (Isolation) [0140] PdCl2(PhCN)2 (0.06 mmol, 0.023 g), CuCl2*2H2O (0.06 mmol, 0.0102 g) and AgNO2 (0.03 mmol, 0.0046 g) were weighed into a 20 mL vial charged with a stir bar. The vial was sparged for 2 minutes with oxygen (1 atm, balloon). Premixed and oxygen saturated tert-BuOH (7.5 mL) and MeNO2 (0.5 mL) was added followed by the alkene (0.5 mmol) were added in that order via syringe. The solution was saturated with oxygen by an additional 45 seconds of sparging. The reaction was then allowed to stir at room temperature for 6 hours. Next, the reaction was quenched by addition to water (ca. 50 mL) and extracted three times with dichloromethane (ca. 25 mL). The combined organic layers were subsequently washed with a saturated solution of NaHCO3 and dried over Na2SO4. The solvent was removed under reduced pressure and the desired aldehyde product was purified using flash chromatography (pentane/ether). Selectivity was determined from 1H NMR analysis of the

unpurified mixture by ratio of the aldehydic 1H signal to the most clear signal from the methyl ketone (usually the methyl group). Long relaxation delays (d1=15) were applied due to the long T1 of the aldehydic proton signal. Example 3.1.2 Procedure (B) for Smaller-Scale (0.2 Mmol) Oxidation of 1-Dodecene (GC Analysis) [0141] PdCl2(PhCN)2 (0.024 mmol, 0.0092 g), CuCl2*2H2O (0.024 mmol, 0.0041 g) and AgNO2 (0.012 mmol, 0.0018 g) were weighed into a 2 dram screw-cap vial charged with a stir bar. The vial was sparged for 45 seconds with oxygen (1 atm, balloon) then subsequently tridecane (0.00246 mmol, 6 μL), tert-BuOH (3 mL), MeNO2 (0.2 mL) and 1-dodecene (0.2 mmol, 44.4 μL) were added in that order via syringe. The solution was saturated with oxygen by an additional 45 seconds of sparging. The reaction was then allowed to stir at room temperature for 6 hours. Next, an aliquot (ca. 0.2 mL) was injected into a 2 mL vial containing an estimated 1 mL of premixed EtOAc/pyridine solution (3:1) to quench the reaction. The resulting solution was subsequently subjected to GC analysis to determine yield and selectivity. Example 3.1.3 Procedure (C) for Small-Scale (0.2 Mmol) Oxidation of Alkenes (NMR Analysis) [0142] PdCl2(PhCN)2 (0.024 mmol, 0.0092 g), CuCl2.2H2O (0.024 mmol, 0.0041 g) and AgNO2 (0.012 mmol, 0.0018 g) were weighed into a 2 dram screw-cap vial charged with a stir bar. The vial was sparged for 45 seconds with oxygen (1 atm, balloon) then subsequently tert-BuOH (3 mL), MeNO2 (0.2 mL) and alkene (0.2 mmol) were added in that order via syringe. The solution was saturated with oxygen by an additional 45 seconds of sparging. The reaction was then allowed to stir at room temperature for 6 hours. Next, the reaction mixture was diluted with water (ca. 20 mL) and subsequently extracted three times with CDCl3, dried with Na2SO4 and concentrated under reduced pressure for 1H NMR analysis. Immediately prior to NMR analysis nitrobenzene was added as an internal standard. The resulting solution was subsequently subjected to 1H NMR analysis to determine yield and selectivity by ratio of the aldehydic 1H signal to the most clear signal from the methyl ketone (usually the methyl group). Long relaxation delays (d1=15) were applied due to the long t1 of the aldehydic proton signal. Example 3.1.4 Procedure (D) for Stoichiometric Oxidation of 1-Dodecene (GC Analysis) [0143] PdCl2(PhCN)2 (0.024 mmol, 0.0092 g), CuCl2.2H2O (0.024 mmol, 0.0041 g) and AgNO2 (0.012 mmol, 0.0018 g) were weighed into a 2 dram screw-cap vial charged with a stir bar. The vial was sparged for 45 seconds with oxygen (1 atm, balloon) then subsequently tridecane (0.00246 mmol, 6 μL), tert-BuOH (3 mL), MeNO2 (0.2 mL) and 1-dodecene (0.024 mmol, 5.3 μL) were added in that order via syringe. The solution was saturated with oxygen by an additional 45 seconds of sparging. The reaction was then allowed to stir at room temperature for 3 hours and 30 minutes. Next, an aliquot (ca. 0.2 mL) was injected into a 2 mL vial containing an estimated 1 mL of premixed EtOAc/pyridine solution (3:1) to quench the reaction. The resulting solution was subsequently subjected to GC analysis to determine yield and selectivity. Example 3.1.5 Procedures for Variation of Oxygen Atmosphere [0144] A series of experiments to determine the effect of oxygen atmosphere were conducted, the results being shown in the following Table 1: Based on these data, and without being necessarily bound by the correctness of any particular theory or statement, it appeared that oxygen was the terminal oxidant and sole stoichiometric reagent in this system. Although reaction sealed under air resulted in acceptable yield (60percent, see Table 1), the rate and conversion improved significantly under an oxygen atmosphere. Further increase in oxygen pressure (3 atm) did not provide increased efficiency but did marginally increase the selectivity. [TABLE-US-00001] TABLE 1 Oxygen atmosphere variation Overall yield entry Conditions (aldehyde yield) selectivity 1 no O2 (argon) 12 (10) 80percent 2 air (sealed) 60 (48) 79percent 3 air (open) 38 (27) 71percent 4 O2 (1 atm) 80 (63) 79percent 5 O2 (3 atm) 68 (58) 84percent [0145] Entry 1: Conducted as described in procedure B except using a balloon filled with argon (1 atm) in place of a balloon filled with oxygen. [0146] Entry 2: Conducted as described in procedure B except the reaction was never exposed to pure molecular oxygen. [0147] Entry 3: Conducted as described in procedure B except the reaction was never exposed to pure molecular oxygen and the vial was left uncapped. [0148] Entry 4: Conducted as described in procedure B with no deviation. [0149] Entry 5: Conducted in an open vial placed inside a Fischer porter bottle connected to an oxygen tank and adjusted to 3 atm O2. Example 3.2 Effect of Reaction Parameters (FIG. 3A) [0155] Various redox catalysts, ligands, redox catalysts, palladium sources and a wide variety of additives were investigated. Each of the type of palladium and copper complexes, and the types of oxygen-centered radical species were found to play an important role in the overall performance of the catalytic system, as did the choice of solvent. Removal of any of these components results in dramatically poorer conversion, selectivity, or both. [0156] In one variation of Procedure D, experiments were conducted with the omission of either copper or palladium. The GC was monitored over 3 hours and 30 minutes. When palladium was omitted: no conversion was observed. When copper was omitted: 33percent yield (combined aldehyde and ketone) was observed with 53percent ketoneselectivity. As a reference point, the analogous reaction with DMF/water and no AgNO2 has proceeded to complete conversion with complete ketone selectivity within this time. The results are shown in FIG. 3B. [0157] Removal of copper from the process provided only traces of products. Exposure of alkene to stoichiometric palladium and silver nitrite, however, also provided incomplete oxidation and poor selectivity, suggesting a more intimate role of the copper salt than a simple redox catalyst for palladium (FIG. 3B). Furthermore, stoichiometric copper dichloride and silver nitrite (no palladium) provided no conversion of the alkene. Thus, it appears that both palladium and copper are crucial metals for the efficient stoichiometric oxidation of alkenes. Ag(I) salts have been shown to be non-innocent additives (potential oxidants) in palladium-catalyzed reactions. However, if AgNO2 was replaced by NaNO2, a similar reaction outcome was observed with marginally lower selectivity (FIG. 3C). This strongly implied that nitrite was the critical component of the co-catalyst, not Ag(I). [0158] Detailed reaction profiles employing various quantities of AgNO2 (FIG. 3D) were generated to study the effect of time on the reaction. Increased loading of AgNO2 correlated with a faster reaction, implying a rate dependence on AgNO2 concentration. A similar overall yield of aldehyde was obtained using both 12 and 6 mol percent AgNO2, with slightly improved aldehyde yield using 6 mol percent. Interestingly, even 2 mol percent AgNO2 provided useful yields of aldehyde after a longer reaction time. Omission of AgNO2 led to a process not exceeding 20percent overall yield. [0159] In a related series of experiments, Procedure B was used to measure the progress of the reaction with time. Time points were collected with a Freeslate (formerly Symyx) software system at the given times and quenched with a 3:1 mixture of EtOAc and pyridine, followed by GC analysis using tridecane as an internal standard. Reaction temperature is further maintained at 20° C. throughout the course of the reaction. Variation of nitrite loading was accomplished with no further deviation from protocol B. After GC analysis, the data was processed and graphed using Microsoft Excel. See again FIG. 3D. [0160] In contrast to previous attempts by others to develop and aldehyde-selective Wacker-type oxidation, that have been plagued by low yields and loss of selectivity over the course of the reaction, in the present experiments, tests with 1-dodecene showed the selectivity stabilized after 5percent conversion and became relatively independent of both yield and time. See FIG. 3E. [0161] Other nitrite sources, including organic and inorganic derivatives, were evaluated by Procedure B. Catalytic AgNO2 was found to provide the highest selectivity among nitrite sources (see Table 2). [TABLE-US-00002] TABLE 2 Nitrite sources (obtained by procedure B) Overall yield entry Conditions (aldehyde yield) selectivity 1 tert-BuONO 75 (41) 55percent 2 n-BuONO 76 (34) 45percent 3 NOBF4 73 (42) 59percent 4 Pd(NO2)Cl(MeCN)2 80 (21) 29percent 5 AgNO2 80 (63) 79percent 6 NaNO2 82 (61) 75percent [0162] From these studies, co-catalytic nitrite salts were found to provide unparalleled reactivity in the presence of palladium and copper. Intriguingly, when the reaction was conducted in an open vessel, both yield and selectivity were significantly worse than when sealed under air. (see Table 1). [0163] The introduction of a small amount of a polar co-solvent, nitromethane, both increased homogeneity of the reaction mixture and enabled room temperature reaction. Once optimized, the new conditions (PdCl2(PhCN)2 (12 mol percent), CuCl2*2H2O (12 mol percent), AgNO2 (6 mol percent) in tert-BuOH/MeNO2 (15:1) under 1 atm oxygen) oxidized 1-dodecene to dodecanal in 63percent yield (see also FIG. 2A/2B and FIG. 3A). Example 3.5 Characterizations of Products in Table 3 [0166] Dodecanal (Table 1, Entry 2) [0168] 61percent yield obtained using procedure A. 1H NMR (500 MHz, CDCl3) δ 9.76 (t, J=1.9 Hz, 1H), 2.43 (td, J=7.4, 1.9 Hz, 2H), 1.64 (tt, J=7.5, 7.5 Hz, 2H), 1.49-1.18 (m, 16H), 0.97-0.77 (t, J=6.8, 3H). Spectral data were in accordance with a commercial sample.
