Abstract
Mono and di-N-trifluoroacetylation of ortho-arylenediamines can be performe d selectively under ultrasound irradiation according to the relative amount s of starting materials. Mono and di-trifluoroacetylated compounds 3 and 4 are prepared with good yields in dry THF during 1 to 2 min sonication. (C) 2000 Elsevier Science Ltd. All rights reserved.
