Structural isomerization of (bis(trimethylsilyl)amino)phosphine oxides
Neilson, Robert H.,Jacobs, Richard D.,Scheirman, Russell W.,Wilburn, James C.
, p. 1880 - 1882 (1978)
The reactions of lithium bis(trimethylsilyl)amide with phosphoryl chlorides ClP(O)X2 (X = F, Cl, Ph) result in the formation of the N-silylated phosphinimines Me3SiN=PX2OSiMe3 rather than the isomeric phosphine
