✦ Synopsis


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