N-Aryl- and N-alkylhexafluoroisopropylideneimines (2) were prepared from the hexafluorothioacetone dimer (1) by treatment with either aryl- or alkylamines. These imines reacted with alcohols and thiols to give three addition products, 7, 8, and 9. Phenylhydrazone (3), semicarbazone (4), hydrazone (5), and azine (6) of hexafluoroacetone were also obtained directly from 1 and the corresponding carbonyl reagents.

The reaction of N-arylimines of hexafluoroacetone and CF3Si(CH3)3 (1) in the presence of CsF results in a 48–84% yield formation of ArN(H)C(CF3)3. The reaction requires an equimolar amount of CsF and rapidly proceeds in solvents such as THF or monoglyme. Interaction of CF3NC(CF3)2 with excess of 1 leads to the formation of novel amine [(CF3)3C]2NH. Stable salt of this amine is isolated in a reaction
