A CONVENIENT SYNTHESIS OF N-ALKYL AND N,N-DIALKYLTRIFLUOROACETAMIDES IN A SOLID-LIQUID TWO-PHASE SYSTEM IN THE PRESENCE OF PHASE-TRANSFER CATALYSTS

Landini, Dario,Penso, Michele

, p. 791 - 800 (2007/10/02)

Trifluoroacetamide is easily monoalkylated in a K2CO3-organic solvent solid-liquid two-phase system affording in good to excellent yields N-alkyltrifluoroacetamides.Under the same conditions, the latter, in turn, ract with alkylating agents giving N,N-dialkyltrifluoroacetamides in high yields.
