Abstract
Treatment of ethanethiol esters with triethylsilane and palladium on carbon at ambient temperature furnished aldehydes. In addition, a variety of ketones has been prepared by a palladium-catalyzed reaction of ethanethiol esters with organozinc reagents. Both transformations tolerate various functional groups, including esters, ketones, aromatic halides and aldehydes.
