Abstract: | The first isolation of a phosphonium amide, (Ph3PEt)+(NPh2)−, obtained via the deprotonation of a secondary amine (diphenylamine) with a phosphorus ylide (triphenylphosphonium ethylide), is described. An X-ray crystal structure provides the first observation of an essentially ion-separated Ph2N− anion in the solid state, though weak association with Ph3PEt+ cations take plac through C---H…N hydrogen bonding. Cryoscopic and NMR spectroscopic data suggest that this association is not maintained in benzene solution. |
