NN-difluoroamines. An aromatic ring that is not deactivated towards electrophilic attack reacts in preference to an amide. Conversion of amides into the more reactive imino-ethers overcomes this problem. This is illustrated by the synthesis of the NN-difluoro-derivatives of amphetamine and tyramine. Evidence is presented for the mechanism of these reactions.

Schiff's bases react smoothly with CF3OF to afford, in alcoholic media, NN-difluoroamines; the reaction provides a convenient conversion of amines into NN-difluoroamines under mild conditions.
