The complexes [(η6-arene)RuCl2(Cy 2PCH=CH2)], [arene = MeC6H5, (1a); p-MeC6H4Me; (2a); p-MeC6H4CHMe 2, (3a); 1,2,4,5-Me4C6H2, (4a); and C6Me6, (5a)], have been synthesized by reacting [(η6-arene)RuCl2]2 with dicyclohexylvinylphosphine (DCVP). In the presence of AgPF6, in a 1: 1 dichloromethane/acetone solvent mixture the compound [(η 6-C6Me6)RuCl2(Cy 2PCH=CH2)] (5a) afforded [(η6-C 6Me6)RuCl(η3-DCVP) ]PF6 (1b). A similar reaction was conducted with [(η6-C6Me 6)RuCl2(Ph2PCH=CH2)] in an attempt to form [(η6-C6Me6)RuCl(η 3-DPVP)]PF6 (2b). However, this reaction yielded, instead, the unexpected trinuclear heterobimetallic complex [{(η6-C 6-Me6)Ru(μ-Cl)2(Ph2PCH=CH 2)}2Ag](PF6) (3b) the structure of which was determined by X-ray crystallography. Compound (1b) reacts with phenylisocyanide to form [(η6-C6Me6)RuCl(η 1-DCVP)(CNPh)]PF6. The complexes have been characterized by 1H, 31P{1H} and 13C{ 1H} NMR spectroscopy, elemental analyses, cyclic voltammetry, and in some cases [compounds (4a), (1b) and (3b)] by X-ray crystallography.
