C6H5, Me3Si, cleave the SiC2 ring of hexamethylsilirane in an exothermic reaction at room temperature to give silylphosphines, R2PSiMe2(CMe2CHMe2). Methylphosphine reacts similarly. The reaction of the silirane with RPCl2 (R = Me, Et, Ph) proceeds differently, giving Me2SiCl2, Me2CCMe2 and cyclo-[RP]5. With Ph2PCl, the reaction with the silirane gives Ph2PPPh2.
室温下,放热反应中的仲膦R 2 PH(R = CH 3,C 6 H 5,Me 3 Si)裂解六甲基甲硅烷基的SiC 2环,得到甲硅烷基膦R 2 PSiMe 2(CMe 2 CHMe 2)。 。甲基膦的反应类似。与RPCL的silirane的反应2(R =甲基,乙基,PH)进行不同的,让我2的SiCl 2中,Me 2 CCMe 2和环- [RP] 5。在Ph 2 PCl中,与甲硅烷基的反应得到Ph2 PPPh 2。
