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).
