A Facile Method for the preparation of 1,1-Dichloroolefins Using Benzenesulfonylchloride as a Chlorenium Ion Source

Reaction of the lithio anion derived from diethyl methylphosphonate with benzenesulfonyl chloride gives directly the (diethylphosphoryl)dichloromethyllithium. In situ reaction with aldehydes or ketones gives in high yields of 1,1-dichloroolefins in a convenient one-pot procedure.
