Abstract: 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. Keywords: α-arylthio esters; α-arylthio ketones; CÀ C bond cleavage; copper catalysis; diaryl disulfides α-Thioaryl carbonyl compounds are useful intermediates in ...
