Complexes of the type [Pd2(μ-Cl)2R2L2] (R = Ph, C6H4Me-p, or CH2Ph; L = PPh3, PMePh2, or PBu3) are prepared by the reaction of R2Hg with [Pd2(μ-Cl)2Cl2L2] in benzene and have been characterized by elemental analysis and NMR spectroscopy. Reaction with L gives the corresponding bis(phosphine)palladium complex, while treatment with CO yields [Pd2(μ-Cl)2(COR)2L2]. Carbonylation of trans- [PdClRL2] or bridge cleavage of [Pd2(μ-Cl)2(COR)2L2] with L produces trans-[PdCl(COR)L2]. The rates of these processes are considered, and the intermediacy of the dimeric complexes in the carbonylation of trans-[PdClRL2] is discussed.
