Polyfluorophosphinazines in the synthesis of asymmetric polyfluoroketazines
摘要:
A new method has been developed for the preparation of asymmetric polyfluoroketazines based on the reaction of polyfluorodialkyl ketone trialkylphosphinazines with perhaloketones. 1-Hydro-1,1,5,5-tetra(trifluoromethyl)-2-pentafluoroethyl-3,4-diaza-2,5-pentadiene and 1-hydro-1,1,5-tri(trifluoromethyl)-5-difluorochloromethyl-2-pentafluoroethyl-3,4-diaza-2,5-pentadiene were obtained in high yield.
