Abstract

The cyano(triphenylsilyl)phosphanide anion was prepared as a sodium salt from 2-phosphaethynolate. The electronic structure of this new cyano(silyl)phosphanide was studied via computational methods and its reactivity investigated using various electrophiles and Lewis acids, demonstrating its P- and N-nucleophilicity. The ambident reactivity is in agreement with computations. The silyl group also shows lability and therefore the cyano(silyl)phosphanide can be considered as a phosphacyanamide synthon, [PCN] , and serves as building block for the transfer of a PCN moiety.

摘要

氰基（三苯基硅基）磷化物阴离子由2-磷乙炔醇盐制备成钠盐。通过计算方法研究了这种新型氰基（硅基）磷化物的电子结构，并使用各种亲电试剂和路易斯酸研究了其反应活性，证明了其P-和N-亲核性。这种两可亲核反应活性与计算结果一致。硅基也表现出不稳定性，因此氰基（硅基）磷化物可被视为磷氰酰胺合成子[PCN]，并作为转移PCN部分的结构单元。
