Abstract: Aseries of symmetrical biaryls was synthesized from arylmercuric chlorides and biarylmercurials in the presence of [ClRh(CO)2]2 in hexamethylphosphoramide(HMPA). The mechanism of the [ClRh(CO)2]2 catalyzed dimerization of biarylmercurials was studied, and shown to be mainly intermolecular reaction.

Key words: Symmetrical biaryls, Synthesis, Arylmercurials, Intermolecular reaction
