The reaction of trifluoroacetyl amides with Grignard reagent for the substitution of CF3 group with various alkyl or aryl groups is described. A variety of aryl, quinolin-8-yl, and (hetero)alkyl functional groups as well as F, Cl, and Br atoms are well tolerated. These moisture-stable and easily available trifluoroacetyl amides can be conveniently obtained and used as new versatile precursors for isocyanates. The control experiments show that the reaction proceeds via an isocyanate intermediate and/or alkoxide/amide dual anionic intermediate.

(N-Aryltrifluoroacetimidoyl)zinc halides were easily generated at room temparature by the oxidative addition of imidoyl halides to activated zinc powder. zinc halides react with aldehydes to give the corresponding alcohols smoothly to excellent yields.These adducts could be readily transformed to the α-amino ketones.
