摘要：

The reaction of mer-[ReL(O)Cl-3], [L = 2-(p-chlorophenylazo)-1-methylimidazole] with Ph2P(CH2)(n)PPh2 (abbreviated PnP) affords [ReL(OP1P)Cl-3] 2a, [ReL(OP1PO)Cl-3] 4 and [ReL(OP2P)Cl-3] 2b, [Cl3LRe(OP2PO)ReLCl3] 5, all having mer geometry; unlike 2b which is stable in solution, 2a spontaneously isomerizes to fac-[ReL(P1PO)Cl-3] via an associative pathway; the origin of the observed differentiation (2a vs. 2b and 4 vs. 5) is scrutinized in terms of structures and reaction models.
