, p. 193 - 196 (2007/10/03)
A direct method for the preparation of trifluoroacetimides has been extended to the preparation of trifluoroacetyl trifluoracetimide and the new compound trifluoromethylsulfuryl trifluoroacetimide. Points concerning previously reported syntheses of trifluoroacetyl isocyanate have also been clarified.

It was demonstrated by chromatographic mass spectrometry and NMR and IR spectroscopy that products of the reaction of trifluoroacetic acid with methyl thiocyanate - N-trifluoroacetyl S-methyl thiocarbamate, S-methyl trifluoroethanethioate, and N-trifluoroacetyltrifluoroacetamide - are formed simultaneously in the synthesis of thiocarbamates and esters of thiocarboxylic acids from aliphatic carboxylic acids and the nonisomerized thiocyanates in trifluoroacetic acid.
Reactions of Trifluoroacetyl Isocyanate

Trifluoroacetyl isocyanate (1) can be obtained from trimethylsilyl isocyanate and trifluoroacetyl chloride. 1 reacts with trifluoroacetamide forming N,N'-bis(trifluoroacetyl)urea (2), which can also be obtained from trifluoroacetyl chloride and urea or N,N'-bis(trimethylsilyl)urea, respectively. 1 reacts with ammonia or various amines forming the trifluoroacetylsubstituted ureas 3 - 6, and hydrazine 7.From 1 and trifluoroacetic acid hexafluorodiacetamide (8) could be obtained. 1 reacts with tert-butylalcohol forming tert-butyl (trifluoroacetyl)carbamate (9).From 1 and N,N-dimethylformamide N,N-dimethyl-N'-(trifluoroacetyl)formamidine (10) could be obtained as well as N-(trifluoroacetyl)pyrrole-2-carboxamide (11) from pyrrole.
