The preparation of several vinyl sulfides, selenides and tellurides by Wittig-type reaction in a one-pot procedure is described. The chalcogenyl triphenylphosphoranes 3 are formed 'in situ' by the reaction of chloromethyl phenyl chalcogenide, potassium tert-butoxide and triphenylphosphine. Reaction of 3 with carbonyl compounds affords the vinyl chalcogenides 6-9 with preferential Z-configuration.
