Abstract An efficient method for the preparation of trihalomethyl (Cl, Br) ketones by the oxidation of trihalomethyl carbinols with 2-iodoxybenzoic acid in tert-butanol under heating has been developed. A series of trihalomethyl ketones have been synthesized through a simple, convenient, and environmentally friendly method with excellent yields.

Aromatically substituted acetic acids are prepared by the reaction of an aromatically substituted aldehyde with a combination of a trihalomethane and an alkanethiol, and by the reaction of an alcohol derivative (2,2,2-trihalo-1-arylethanol) with an alkanethiol, in the presence of a base in a mixed medium of water and an aprotic polar solvent.
