Studies on the Mechanism of Dimerization of Organomercuric Compounds by Rhodium(Ⅰ)

Abstract

Abstract: The kinetics of dimerlzation of β-naphthylmercuric chloride in the presence of[CIRh (CO)₂]₂ has been studied in hexamethylphosphoramide. The dimerization has beenfound to be second order and the kinetic parameters of the dimerization have been reported.Both α-naphthylmercuric chloride and α-bromomercuriphenylacetate have not beendimerizated under the same reaction conditions, which has been explained on the basis of the proposedmechanism. The organic rhodium (I) intermediate formed in the α-bromonercuriphenylacetate case was isolated and identified.

Key words: Naphthylmercuric chloride, Rhodium(Ⅰ) catalyzed dimerization, Kinetics
