The effectiveness of thirteen largely applied procedures has been checked in the oxidation of 1,1,1-trichloropropan-2-ol. A new, simple, and efficient modification using chromic acid has been found for the preparation of representative trichloromethyl ketones.
A ruthenium complex RuCl[(S,S)-Tsdpen](p-cymene) represented by a formula below and a ketone compound are placed in a polar solvent, and the resulting mixture is mixed under pressurized hydrogen to hydrogenate the ketone compound and to thereby produce an optically active alcohol:
