Abstract

Vinylmercuric chlorides undergo reaction with palladium chloride and lithium chloride in hexamethylphosphorarnide at 0" C to provide essentially quantitative yields of the corresponding symmetrical conjugated dienes. This reaction is especially valuable for the synthesis of functionally substituted dienes and symmetrical polyenes. Divinylpalladium species are presumed to be intermediates in these reactions.
