Copper‐Catalyzed Synthesis of α‐Thioaryl Carbonyl Compounds Through SS and CC Bond Cleavage

A method to access α‐thioaryl ketones and α‐thioaryl esters employing copper acetate (hydrate) as catalyst and readily accessible diaryl disulfides and β‐diketones (or β‐keto esters) has been developed. Both alkyl‐ and aryl‐substituted carbonyl compounds can be prepared. magnified image
