ORGANIC AMINE-IMINE COMPOUNDS .9. ORGANOMETALLIC AMINOPHOSPHINIMINES

Oxidation of aminophoshines by trimethysilyl azide yields N-silylated aminophosphimines, which can be alcoholized, metalated and transformed into different substituted N-and N,N′ -organometallic aminophosphinimines [(CH3)3C]2- P[N-M(CH3)3](NHR): A (R = H), B (RCH3);[(CH3)3C]2P[N-M(CH3)3]- [NRM′(CH3)3]:C(RH), D(RCH3);[(CH3)3C]2P[N-M(CH33][N(CH32]: E(M = M′= Si,Ge,Sn).D forms stable N,N′-organometallic aminophosphinimine isomers and can be used as '1H NMR reference signal to identify (CH33M ligands which are bonded to immune or amine nitrogen atoms. © 1969.
