Bis(ylide)-substituted phosphenium and phosphonium halides

The bis(triphenylphosphoniumylidyl)halophosphines expected from the condensation of ylidyl dihalophosphines with trimethylsilyl ylides or of their addition to carbodiphosphoranes enter a spontaneous dissociation to yield bis(ylidyl)phosphenium halides.The

Spontaneous dissociation of phosphoniumylidyl-chlorophosphines to ionic phosphenium chlorides

The products from the replacement of two chlorofunctions of PCl3 by a pair of phosphoniumylidyl substituents or by both a phosphoniumylidyl and an amino substituent are ionic phosphenium chlorides and not covalent chlorophosphines.
