Synthesis of the sodium diphenylbis(cyanamido)phosphonium diylide by a new variation of the Staudinger reaction

Abstract

The first example of a stabilized diaminophonium diazaylide, sodium diphenylbis(cyanamido)phosphonium diylide, has been synthesized by a new variation of the Staudinger reaction; the corresponding copper complex can be described as a discrete dimeric unit with [Ph₂P(NCN)₂]^– in both uni- and bi-dentate modes (X-ray structure).
