phosphite (PhO)2PN(Et)P(OPh)2(etdp) in benzene leads to successive replacement of the diene ligands and the formation of [Rh2(diene)(etdp)Cl2] and [Rh(etdp)Cl}2]. The corresponding bromo- and iodo- derivatives [Rh(etdp)X}2](X = Br or I) are produced analogously. Reactions of [Rh(C8H12)Cl}2] with excess of etdp in ethanol or methanol in the presence of a suitable counter ion effects not only the displacement
