Gg. Bargamov et al., POLYFLUOROPHOSPHINAZINES IN THE SYNTHESIS OF ASYMMETRIC POLYFLUOROKETAZINES, Bulletin of the Russian Academy of Sciences, Division of Chemical Sciences, 41(7), 1992, pp. 1277-1279
A new method has been developed for the preparation of asymmetric poly
fluoroketazines based on the reaction of polyfluorodialkyl ketone tria
lkylphosphinazines with perhaloketones. ethyl)-2-pentafluoroethyl-3,4-
diaza-2,5-pentadiene and methyl-2-pentafluoroethyl-3,4-diaza-2,5-penta
diene were obtained in high yield.
