已证明反式[MCL(CO)L2]和[MCl3(CO)L2]，M=Rh或Ir，L=PMe2Ph或Pet2Ph的配合物可能通过双氯桥联中间体相互反应，并经历快速的氧化加成-还原消除；膦交换要慢得多。用反式[MCL(CO)(PEt3)2]、M=Rh或Ir处理反式[PtCl4(PEt3)2]时，也得到了类似的结果，从而快速而完全地转化为反式[PtCl2(PEt3)2]和[MCl3(CO)(PEt3)2]。磷-31nm.r.给出了数据。
Complexes of the type trans-[MCl(CO)L2] and [MCl3(CO)L2], M = Rh or Ir, L = PMe2Ph or PEt2Ph, have been shown to react with each other, presumably by a double chloro-bridged intermediate, and undergo rapid oxidative addition–reductive elimination; phosphine exchange is much slower. Similar results were obtained when trans-[PtCl4(PEt3)2] was treated with trans-[MCl(CO)(PEt3)2], M = Rh or Ir, for which rapid and complete conversion into trans-[PtCl2(PEt3)2] and [MCl3(CO)(PEt3)2] occurred. Phosphorus-31 n.m.r. data are given.
