Method of Preparing Fluoroalkylaminophosphines,
Abstract
The Russian patent concerns the method of preparing fluoroalkylaminophosphines by interacting chlorophosphines with ammonium with cooling. The synthesis is distinguished by the fact that in order to expand the raw-material base and the selection of final products which are useful for synthesizing polymers resistant to heat and aggressive media, alkyl-(fluoroalkyl) perfluoroalkylchlorophosphines are used as the chlorophosphine reagent; the process is conducted at a temperature of minus 30 to minus 40 degrees centigrade; the process is conducted with an excess of liquid ammonium; and the process is conducted in a medium of organic solvent, e.g., isopentane.
