YieldReaction ConditionsOperation in experiment
95% With chromium(VI) oxide; palladium dichloride; In water; acetonitrile; at 20 - 60℃; for 6.5h; General procedure: To a stirred solution of olefin (0.4mmol) in CH3CN (3.5mL) and H2O (0.5mL) were added PdCl2 (3.6mg, 0.02mmol, 5mol%) and CrO3 (20mg, 0.6mmol, 0.5equiv) at room temperature. The reaction mixture was warmed to 60C and stirred for specified time (see Tables 5-7) in a closed flask. The reaction mixture was then filtered through a small pad of silica gel and washed with EtOAc and the filtrate concentrated. The residue in some cases contained virtually pure compound and no further purification was necessary. In other cases the residue was purified by silica gel column chromatography using petroleum ether/EtOAc as an eluent to afford the methyl ketones.
86% With tert.-butylhydroperoxide;silver(I) hexafluorophosphate; [Pd(Quinox)Cl2]; In dichloromethane; water; at 0 - 20℃; for 0.333333h;Protection from light;Product distribution / selectivity; General TBHP Mediated Wacker Reaction:Table 1 reports individual examples while the following description provides a common reaction scheme used in each example with deviations noted. In the dark, AgSbF6 (51.5 mg, 0.15 mmol), Pd(quinox)Cl2 complex (22.5 mg, 0.06 mmol), and a magnetic stir bar were added to a 100 mL round bottomed flask. DCM (4.8 mL) was added to the flask and the mixture was stirred for 15 min. The mixture was then diluted with DCM (20 mL) and 70 wt % TBHP(aq) (5.2 mL, 36 mmol) was added. The resulting mixture was stirred for an additional 10 min, before being cooled in an ice bath. Once the solution had cooled, the substrate (3.0 mmol) was added with stirring. After 5 min, the ice bath was removed and the reaction mixture was allowed to slowly warm to room temperature. Once TLC indicated complete consumption of starting material, the reaction was quenched with a saturated aqueous solution of Na2SO3 (50 mL) to consume excess TBHP. The mixture was transferred to a separatory funnel and diluted with hexanes (50 mL). The aqueous layer was separated and back extracted with hexanes (25 mL). The combined organics were washed with water (4×25 mL) and brine (50 mL). The combined organic phases were dried over MgSO4, filtered and concentrated under reduced pressure. The crude material was purified by silica gel flash chromatography if necessary; the product containing fractions were combined and concentrated under reduced pressure. The general reaction scheme was as follows:; Several common protecting groups for allylic alcohols were shown to be compatible with these conditions, providing the methyl ketone products in high yields (Table 1, entries 1-4). No aldehyde product was detected in any of these cases by GC or 1H NMR analysis. Thus, the above approach can be substantially free or completely free of undesired aldehyde products. Additionally, silyl protected allylic alcohols proceed to product at a significantly faster rate, allowing for the use of lower catalyst loadings (entry 2). An acetal-protecting group, was stable to Lewis acidic, aqueous reaction conditions (entry 3). A homoallylic alcohol also was converted to the methyl ketone in excellent yield (entry 5).The corresponding ketones were each confirmed using NMR, IR and HRMS analyses. The 2-oxooctan-3-yl acetate, 3-(tert-butyldimethylsiloxy)octan-2-one, 3-(ethoxymethoxy)octan-2-one, 1-cyclohexyl-2-oxopropyl acetate, 4-(tert-butyldimethylsolxy)-4-phenylbutan-2-one, 2-decanone, methyl 10-oxoundecanoate, 6-(2,2-dimethyl-1,3-dioxolan-4-yl)hexan-2-one, 11-chloroundecan-2-one, 1-p-tolyethanone were recovered as colorless oils. The 11-hydroxyundecan-2-one, tert-butyl 4-acetylphenylcarbamate, and 1-(3-nitro)ethanone were recovered as a white solid having a melting point of 39-40 C., 113-114 C., and 68-70 C., respectively. Similarly, 11-hydroxyundecan-2-one was isolated as a white solid.The catalytic system was further evaluated to determine whether it was a general catalyst for the Wacker oxidation. Excitingly, the current system rapidly consumes decene leading to 2-decanone in good yield with no appreciable amounts of internal isomers (entry 6). Lowering the amount of TBHP led to conversion of decene without significant loss of yield or increase in isomerization (entry 7). Other functional groups were evaluated including an alkene with a free distal alcohol, which was used to demonstrate the scalability of the reaction using a reduced catalyst loading (entries 8 and 9). Additionally, alkenes containing common functional groups including a methyl ester, acetonide, and primary chloride are well tolerated (entries 10-12). A number of styrene derivatives, another challenging substrate class for the Tsuji-Wacker oxidation, were also evaluated. Substituted styrenes with various functional groups were efficiently oxidized, although a highly electron-deficient system led to a lower yield and a trace amount of m-nitro benzaldehyde (entries 13-15). It should be noted that these reactions are exothermic; therefore the oxidations were initiated at 0 C.
With copper(II) choride dihydrate; hydrogen; oxygen; In N,N-dimethyl acetamide; water; at 80℃; under 760.051 Torr; A DMA solution containing 1.0 mmol of 1 -decene is prepared, and 0.05 mmol of a Pd catalyst, (0.15 mm of) copper (II) chloride dihydrate, and a small amount of H2 are added thereto to make a suspension and to be stirred in an oxygen gas atmosphere at 1 atmospheric pressure for several hours. The catalyst is then removed from the suspension by filtration. Subsequently, the filtrate is concentrated for purification by column chromatography to obtain 2-decanone as an oxidation product.

Zeolite (H) (100 mg) was added to the well stirred solution of alkyne (2 mmol) and H2O (8 mmol) and the reac-tion mixture was allowed to stir at 100 C. After disappearance of the alkyne (monitored by TLC) or after an appropriate time, the reaction mixture was cooled to room temperature, diluted with ethyl acetate. The catalyst was separated by filtration and the removal of solvent in vacuo yielded residue. and it was further puri-fied by column chromatography using silica gel (100-200 mesh) to afford pure products. All the products were identified on the basisof H1 and C13NMR spectral data.
78% With Perfluorooctanesulfonic acid; C8AgF17O3S*H2O; In water; at 100℃; for 8.0h;Darkness; General procedure: To the mixture of phenylacetylene (1 mmol), water (3.0 mL),silver perfluorooctanesulfonate (5 mol%) and perfluorooctane sulfonateacid (2 mol%) was added. The mixture was stirred at 100 Cfor 8 h. The solution was extracted with n-hexane (diethyl ether)(3 5 mL), the combined extract was dried with anhydrous MgSO4. The rest of the solution was used for the next cycle of reaction. Theextraction solvent was removed and the crude product was separatedby column chromatography to give the pure sample.
37%Chromat. With sulfuric acid; C18H15CoN2O10S2(2-)*2Na(1+); water; In methanol; at 80℃; for 20.0h;Schlenk technique; General procedure: The 10 mL schlenk tube was charged with phenylacetylene (0.5 mmol, 51 mg), methanol (0.625 mL), catalyst (10 mumol, 2.0%), and then H2SO4 (10 mumol, 2.0%) dissolved in H2O (2.2mmol, 0.04 mL). The mixture was heated to 80 C and at it for 20 h in a closed tube with a magnetic stirring bar. The progres sof the reaction was monitored using TLC and GC-MS. After the reaction, the mixture was cooled to room temperature, and CH2Cl2 (5 mL) and water (5 mL) were added to the mixture.The aqueous and organic layers were separated, and the aqueous phase was extracted with CH2Cl2 (5 mL 3). The combined organic extracts were washed with a saturated NaCl solution,dried over Na2SO4, and concentrated under reduced pressure. Then the product acetophenone was obtained.

The mineral oil is removed by washing with hexanes. Anhydrous dimethyl sulfoxide (500 ml) is added to the flask and heated to 70° C. until evolution of hydrogen stops. The reaction mixture is cooled to room temperature followed by addition of 1L of anhydrous tetrahydrofuran. (6-hydroxyhexyl) triphenylphosphonium bromide (443.4 g, 1 mol) is slurried with warm anhydrous dimethyl sulfoxide (50° C., 500 ml) and slowly added to the reaction mixture thru the dropping funnel while keeping the reaction at 25-30° C. The reaction is stirred for 30 minutes at room temperature at which time 2-decanone (171.9 g, 1.1 mol) is slowly added thru a dropping funnel. Reaction is slightly exothermic and cooling is needed to maintain 25-30° C. Mixture is stirred for 18 hrs. and then poured into a separatory funnel containing 600 ml of purified water and 300 ml of hexanes. After shaking the oil phase (top) is allowed to separate out and the water phase is removed. The extractions of the oil phase are continued using water until both phases are clear. The organic phase is collected, vacuum distilled and purified by liquid chromatography (90:10 hexanes:ethyl acetate, silica gel stationary phase) to obtain a clear, oily product (119.1 g).

The autoclave was sealed, pressurized with 10-25 bar of H2, N2, or CO and heated to 230 °C for 1000 min (corresponding to ~ 16 h at the reaction temperature); the temperature typically stabilized between 225 and 235 °C. When the system had cooled to room temperature, the pressure was released, the reaction mixture was filtered to remove a black precipitate and analyzed by GC (for determination of conversion and yields) and GC-MS (for observation and identification of other products). Comparison of solvents A number of primary or secondary monohydric Ci-Cio alcohol solvents were tested together with NH4V03 as the catalyst. In addition, their performance was compared to that of acetone and hexane as solvents. The yields of 1-decene (C=C), 2-decanone (C=0), 2-decanol (2°OH), and 1-decanol (l°OH) are provided below in Table 1. It is evident that using a primary or secondary monohydric Ci-Cio alcohol as the solvent results in a better selectivity of 1-decene than any of the comparative solvents.
