Abstract

Compounds of the general formula R2C= N–N= PX3 (phosphazines) are readily available through the Staudinger reaction [1]. They have long been used in organic synthesis for identification and purification of liquid and often unstable aliphatic diazo compounds as stable crystalline substances with sharp melting points [2]. In addition, these compounds attract increased interest as diaza analogs of alkylidenephosphoranes R2C= PX3 that are ...
