Alkyl vinyl ketones and divinyl ketones are synthesized from carbonyl compounds and 1-chloro-3-phenylthiopropyl phenyl sulfoxide as a three-carbonhomologatingagent in good overall yields.
Treatment by sulfuryl chloride of the bis-O-TES derivative of a gamma,epsilon-bis-hydroxy phenylsulfoxide resulted in the selective formation of the corresponding gamma-chloro-epsilon-hydroxy phenylsulfone. (C) 1997 Published by Elsevier Science Ltd.
