Salts of the dimethyltetrafluorophospate, [Me2PF4]–, anion

Abstract

Stable phosphiniminophosphonium salts of the hitherto unknown dimethyltetrafluorophosphate anion, [Me2P(NPR3)2]+[Me2PF4]–, have been prepared in the reaction of dimethyltrifluorophosphorane with several N-trimethylsilylphosphine imines.
