Preparation and characterisation of some nitrogen-bridged phosphorus fluorides
Difluorophosphino(tetrafluorophosphoranyl)methylamine, PF2·NMe·PF4, and difluorophosphino(difluorophosphoryl)methylamine, PF2·NMe·POF2, result from the action of difluorophosphino(trimethylsilyl)methylamine on phosphorus pentafluoride and phosphoryl trifluoride respectively. Difluorophosphino(trimethylsilyl)methylamine can be prepared in good yield from chlorodifluorophosphine and heptamethyldisilazene. An alternative route to difluorophosphino(difluorophosphoryl)methylamine is the reaction between methylaminophosphoryl difluoride and chlorodifluorophosphine in the presence of base. Some other routes for these derivatives are described with the properties of these nitrogen-bridged derivatives. Comparable reactions with thionyl fluoride and sulphur dioxide do not yield products containing nitrogen bridges between phosphorus and sulphur atoms. Spectroscopic data are presented for all of these compounds.
