Chemistry of phosphorus fluorides. Part II. Secondary alkylamino derivatives of phosphoryl fluoride

Phosphoryl fluoride reacts with dimethylamine in an equimolar ratio to yield volatile dimethylaminophosphoryldifluoride. The residual solid is a mixture of dimethylammonium hexafluorophosphate and dimethylammonium difluorophosphate salts rather than the simple fluoride salt. Dimethylamine reacts slowly with dimethylaminophosphoryldifluoride to yield bis(dimethylamino)phosphorylfluoride and the same complex fluorophosphate anions in the solid products. Physical data are reported on the alkylamino phosphoryl fluorides. The reaction of the difluorophosphoryl compound with hydrogen halides has been studied.
