Dichloromethane reacts with dinuclear rhodium complexes [{(PR 3 ) 2 Rh} 2 (μ‐Cl) 2 ] to give the bridging‐methylene complexes [{(PR 3 ) 2 RhCl} 2 (μ‐Cl) 2 (μ‐CH 2 )] (PR 3 = PEt 3 , PPh 2 Me). The structure of the PEt 3 complex has been established by X‐ray diffraction study. The early stages of the reaction of [{(C 8 H 14 ) 2 Rh} 2 (μ‐Cl) 2 ] with monophosphanes have been monitored by 31 P NMR, evidencing chloride bridges cleavage and phosphane redistribution processes.
