Typical method for isolation of aldehydes and diketone General procedure: The typical solution containing 1 mmol of substrates, 0.1 mol percent RuCl3 and 3 equiv of PhI(OAc)2, was heated and kept at constant 30°C. After Reaction for a period of time, the mixture was then separated with separatory funnel and the dichloromethane phase was dried over anhydrous Na2SO4, filtered and the solvent removed under vacuum. The crude product was purified via a standard silica gel chromatography using hexanes/ethyl acetate as eluent to give the desired aldehyde and diketone products. The isolated products were characterized by NMR (in CDCl3 with TMS as an internal standard) and ESI-MS. All the reactions were performed at least three times to establish there producibility and reliability.

Conditions & References 1.A : STEP A: STEP A: 1-phenyl-propane-1,2-dione 6.0 kg (44.78 moles) of propiophenone and 92 g of anhydrous aluminum chloride were added to 6 liters of ether followed by 17.2 kg (107.5 mole) of bromine at a rate to maintained a gentle reflux. When the addition was complete (approximately 6 hours), the mixture was heated to reflux overnight and then the solvent was removed under vacuum to obtain a lachrymatory dark red/orange oil. The oil was slowly added to a solution of 2.81 kg (122.2 mmole)of sodium in 45 l of methanol while maintaining the temperature below 20° C. When the addition was complete, 12.5 liters of concentrated hydrochloric acid were added and the mixture was stirred at room temperature for 1 hour. The precipitate was filtered off and the filtrate reduced in volume to approximately 25 liters by distillation of the methanol. The residue was partitioned between 10 liters of chloroform and 10 liters of water. Then, the organic phase was separated and the aqueous phase extracted twice with 5 liters of chloroform. The combined chloroform solutions were dried over sodium sulfate and evaporated to dryness.

4.2. General procedure for the oxidation General procedure: A mixture of a substrate (0.6 mmol), vinyl bromide 2a (0.06 mmol) in DMSO (1.1 mL) was heated in an open flask (the temperature of an oil bath and the reaction time are specified in refPreviewPlaceHolderTable 2). After the completion of the reaction (checked by TLC), the reaction mixture was diluted with water (11 mL), saturated with NaCl and extracted with ethyl acetate (5.x.4 mL). Only in the case of the synthesis of arylglyoxals the organic layer was additionally washed with Na2CO3 (0.12 mmol in 2 mL of water), with saturated aq NaCl and dried with anhydrous Na2SO4. Column chromatography (eluent: gradient petrolether/ethyl acetate) of the extract gave the pure products.

4.5.4. A typical procedure for aerobic oxidation of silyl enol ethercatalyzed by PI-Au 4l. General procedure: 4.5.4. A typical procedure for aerobic oxidation of silyl enol ether catalyzed by PI-Au 4l. Trimethyl(1-phenylprop-1-enyloxy)silane (51.5 mg, 0.25 mmol), PI-Au 4l (0.240 mmol/g, 1 mol percent), toluene (1.0 mL), and water (1.0 mL) were combined in a round-bottom flask. The mixture was stirred for 11 h under O2 at 80 °C. After cooling to room temperature, the catalyst was collected by filtration and washed with ethyl acetate, using a Kiriyamarohto funnel. The aqueous layer was extracted with ethyl acetate (20-30 mL). The combined organic layers were dried over sodium sulfate. The yield was determined by GC analysis with reference to an internal standard (anisole).

Then the reaction mixture was poured into 50 mL brine and the aqueous layer was extracted with EtOAc (3×50 mL). The extract was washed with Na2S2O3 solution, dried over anhydrous Na2SO4 then the solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel using petroleum ether/EtOAc as the eluent to give the expected products 3aa as the yellow solid (240 mg, 85percent yield).

EXAMPLE XIII A solution of 0.4 gram of biacetyl (0.014M) and 1.4 grams of 1-phenyl-1,2-propanedione (0.028M) in 250 milliliters of o-dichlorobenzene was charged to the pressure reactor. Condensed propylene (45.6 grams, 3.20M) was added increasing the pressure to 80 psia. Nitrogen was added to bring the pressure to 150 psia, and oxygen was added to a pressure of 169 psia. Irradiation (450 Watt high pressure mercury lamp) of the vigorously stirred solution for 90 minutes produced 11.2 mmoles of propylene oxide (7.5 mmoles/hr.) as the only product.
