Yield:863305-32-2 81 %Chromat.
Reaction Conditions:
with (carbonyl)(chloro)(hydrido)tris(triphenylphosphine)ruthenium(II);1,1'-sulfinylbisbenzene in tetrahydrofuran at 70; for 2.5 h;Inert atmosphere;Sealed tube;Green chemistry;
Steps:
Typical procedure for the ruthenium hydride-catalyzed direct oxidation of alcohols to carboxylic acids with diphenyl sulfoxide
General procedure: Benzyl alcohol 1a (108.1 mg, 1 mmol), diphenyl sulfoxide 2 (202.3 mg, 1 mmol), [RuHCl(CO)(PPh3)3] (39.1 mg, 0.04 mmol) and THF (2 mL) were placed in a screw capped test tube. The test tube was purged with argon and sealed. The mixture was stirred at 70 °C for 2.5 h. After the reaction was completed, the solvent was removed under reduce pressure. The residue was purified by silica gel chromatography (petroleum ether/ethyl acetate = 6/1) and recrystallized from H2O-methanol to give the compound 3a as a white crystal.
