Abstract:

Perfluromethylcoumarins were synthesized by the reaction of m-substituted phenol and ethyl 4,4,4-trifluoro-2-butynoate or ethyl 4,4,4-trifluoroacetoacetate. The products were analyzed by 1H NMR, 13C NMR, IR, MS and microanalysis. The reaction pathway and mechanism were proposed.

Key words: NMR, Perfluromethylcoumarins, MS, IR, m-substituted phenol
