The reaction of the phosphine oxides, OPEt31 and OPn-Bu32 with pinacolborane (HBpin) results in phosphine oxide reduction and the formation of O(Bpin)23. In contrast, the phosphine oxide OPn-Bu3 reacts with HB(C6F5)2 or B(C6F5)3 to give only the donor–acceptor adducts. Compound 3 reacts with HNPt-Bu3 to give the phosphinimonium borate salt, [t-Bu3PNH2][(Bpin(OBpin)2]
6, while reaction with Cp2ZrMe2 affords the species Cp2Zr(OBpin)27.
磷烯氧化物OPEt3和OPn-Bu3与pinacolborane (HBpin) 的反应导致磷烯氧化物还原并形成O(Bpin)2。相比之下,磷烯氧化物OPn-Bu3与HB(C6F5)2或B(C6F5)3反应仅生成供体-受体加合物。化合物3与HNPt-Bu3反应生成磷铵烷硼酸盐[t-Bu3PNH2][(Bpin(OBpin)2]6,而与Cp2ZrMe2的反应则生成物种Cp2Zr(OBpin)2。
