Cyano(triphenylsilyl)phosphanide As a Building Block for P,C,N Conjugated Molecules
Angewandte Chemie (International ed in English)(2021)
摘要
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](2-), and serves as building block for the transfer of a PCN moiety.
