Sterically overloaded γ3-aminoiminophosphines: Molecular structure and properties of N,N-bis (trimethylsilyl) amino-N′-[2,4,6-tri(t-butyl)phenyl]-iminophosphine

Conclusions X-ray crystallography has been used for the first time to examine the spatial structure of an acyclic compound containing two-coordinated phosphorus with the grouping NP=NAr-(N,N-bis (trimethylsilyl) amino-N-[2,4,6-tri(t-butyl)phenyl]aminophosphine. It has been found that the reduced reactivity of this compound towards proton-donor reagents, and its unusually low tendency to undergo dimerization, are due to the screening of the P=N bond by bulky substituents.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No, 6, pp. 1304–1308, June, 1987.
