A facile method for the preparation of 1,1-dichloroolefins using benzenesulfonyl chloride as a chlorenium ion source

Article abstract of DOI:10.1080/00397919108021066

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.
