Studies on Nitrile Imines : Synthesis of Some (Azomethylene)phosphoranes
Tewari, R. S.,Parihar, P.
, p. 218 - 220 (2007/10/02)
A number of (azomethylene)phosphoranes (IIIa-j) have been prepared in good yields by the nucleophilic addition of triphenylphosphine on a wide range of nitrile imines, generated by the attack of triethylamine on hydrazidoyl halides (I).The structural assi
