Preparation and properties of bis(difluorophosphino)- and tris(difluoro-phosphino)-amine

Abstract

Bis(difluorophosphino)amine, (F₂P)₂NH, and tris(difluorophosphino)amine, (F₂P)₃N, have been prepared by the gas-phase reaction of ammonia, trimethylamine, and chlorodifluorophosphine. The compounds have been characterised by i.r., Raman, n.m.r., mass, and photoeiectron spectroscopy. The tertiary amine reacts with hydrides HX (X = Cl, Br, or I) and H₂Y (Y = O, S, Se, or Te) to give the secondary amine and PF₂X or YPF₂H; OPF₂H, SPF₂H, and TePF₂H decompose further.
