Chemistry of phosphorus pentaselenide. II. Its reaction with amines

Abstract

The reaction of phosphorus pentaselenide with amines may yield, as products, selenophosphoric triamides, (RNH) 3 PSe; alkylammonium diselenophosphoric diamides, (RNH) 2 P(Se)Se − RNH 3 + ; or alkylammonium monoacidbis(diselenophosphoric diamides), {[(RNH) 2 P(Se)Se] 2 H} − RNH 3 + , where R is an alkyl group. The preparation of potassium diselenophosphoric diamides, (RNH) 2 P(Se)Se − K + , is also described.
