The first mixed phosphireneâdinitrogen and phosphireneâdiazenide complexes mer-[ReCl(N2)(PPhCPhCPh)L3] (LÂ =Â PMe2Ph 1a or PMePh2 1b) and [ReBr(NNPh)2(PPhCPhCPh)2(PPh3)] 2 have been prepared by treatment of the corresponding thf solutions of trans-[ReCl(N2)L4] or [ReBr3(NNPh)(PPh3)2] with PPhCPhCPh. Their redox properties have been investigated by cyclic voltammetry in an aprotic medium, at a platinum electrode, and the electrochemical EL and PL parameters estimated for the phosphirene ligand indicating that its overall electron donor/acceptor properties are similar to those of PMePh2.
首例混合
磷烯-二氮和
磷烯-二氮基配合物 **mer-[ReCl(N2)(PPhCPhCPh)L3]** (L = PMe2Ph **1a** 或 PMePh2 **1b**) 和 **[ReBr(NNPh)2(PPhCPhCPh)2(PPh3)]** **2** 已通过分别处理 **trans-[ReCl(N2)L4]** 或 **[ReBr3(NNPh)(PPh3)2]** 的THF溶液与 **PPhCPhCPh** 来制备。它们在非质子性溶剂中、
铂电极上通过循环伏安法研究了其氧化还原性质,并对
磷烯
配体的电
化学EL和PL参数进行了估算,结果表明其整体的电子给体/受体性质与 **PMePh2** 相似。
