A convenient synthesis of N, N-bis (trifluoromethyl) anilines by means of dediazotation reactions of previously unknown aryldiazoniumbis (trifluoromethyl) imides in the presence of CuI salts are described. Properties and applications of N, N-bis (trifluoromethyl) anilines in syntheses of aromatic compounds containing the (CF3) 2N group are presented.
