Conclusions
-
1.
The stable 1,1-bis(trifluoromethyl)hydrazine was synthesized by the thermal decomposition of either tert-butyl bis(trifluoromethyl)carbamate or a solution of bis(trifluoromethyl) carbamic acid azide in the presence of water, and its reaction with perfluoro-2-aza-propene, bis(trifluoromethyl)ketene, and hexafluoroacetone was studied.
-
2.
The dhydration of the adduct of 1,1-bis(trifluoromethyl)hydrazine with hexafluoroacetone by oleum gave hexafluoroacetone bis(trifluoromethyl)hydrazone, the first member of the perfluorohydrazones.
