Abstract

The preparation and properties of cationic arenerhodium(I) complexes of general formula [Rh(diolefin)(?6arene)]ClO4 (diolefin=1,5-cyclooctadiene, tetrafluorobenzobarrelene or trimethyltetrafluorobenzobarrelene; arene = biphenyl or diphenylmethane) are described. These complexes react with the solvated intermediate complex [Rh(diolefin)(Me2CO)x]ClO4 to give homobimetallic [(diolefin)Rh(Ph2CH2)Rh(diolefin)](ClO4)2 derivatives. New heterobimetallic complexes of the type [(diolefin)Rh(Ph2CH2)Cr(CO)3]ClO4 have been synthesized by reaction of Cr(CO)3(?6-Ph2CH2) with the solvated complex [Rh(diolefin)(Me2CO)x]ClO4 or, alternatively by treatment of [Rh(diolefin)(?6-arene)]ClO4 with the complex Cr(CO)3(?6Me3B3N3Me3) in chloroform solution.
