Use
phosphine: A colourless highlytoxic gas, PH3; m.p.-133°C; b.p.–87.7°C; slightly soluble in water.Phosphine may be prepared by reactingwater or dilute acids with calciumphosphide or by reactionbetween yellow phosphorus and concentratedalkali. Solutions of phosphineare neutral but phosphinedoes react with some acids to givephosphonium salts containing PH4+ions, analogous to the ammoniumions. Phosphine prepared in the laboratoryis usually contaminated withdiphosphine and is spontaneouslyflammable but the pure compound isnot so. Phosphine can function as aligand in binding to transition-metalions. Dilute gas mixtures of very purephosphine and the rare gases areused for doping semiconductors.
