Abstract
The preparation of 1-chloro-1-chalcogeno(sulfur, selenium) alkenes by a Wit tig-type reaction in an one pot procedure is described. Chlorochalcogenyl t riphenylphosphoranes are formed in situ by the reaction of dichloromethyl p henylchalcogenide, potassium t-butoxide and triphenylphosphine. They react with aldehydes to give 1-chlorovinyl chalcogenides as a mixture of isomers.
