SYNTHESIS AND STRUCTURE ELUCIDATION OF PERFLUROMETHYLCOUMARINS
含全氟烷基香豆素的合成及其结构表征

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, ~(13)C NMR, IR, MS and microanalysis. The reaction pathway and mechanism were proposed.
