The reaction of vinylboronic acids with vinylmercuric acetates produces symmetrical divinylmercurials in high yield. The reaction can be utilized to prepare functionally substituted mercurials. Attempts to prepare unsymmetrical divinylmercurials resulted in redistribution products yielding symmetrical and unsymmetrical divinylmercury compounds.

Vinylmercurials react with Li2PdCl4 and monocyclic olefins to produce π-allylpalladium compounds or 1,4-dienes if triethylamine is added. Bicyclic olefins afford stable alkylpalladium compounds useful in the synthesis of functionally substituted bicyclic alkanes.
