, p. 2020 - 2023 (2007/10/02)

In the reactions of gem-di(heterocumuleno)alkanes with triphenylphosphoranediylaminotrimethylsilane or N-(trimethylsilyl)diphenylketimine one heterocumulene group (isocyanate or carbodiimide) exhibits pseudohalogen characteristics.A new rearrangement with migration of the N=C(C6H5)2 group was discovered in the azaallyl triad C=N-C.
