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