摘要

Efficient, high yield syntheses of 2, 2, 2-trifluoro-1-(N, N-dialkylaminophenyl)-ethanols (3a, b) and 2, 2, 2-trifluoro-1-(hydroxyaryl) ethanols (6c–g) by reacting Ruppert's reagent,( trifluoromethyl) trimethylsilane (TMSCF3), with appropriate substrates in the presence of a catalytic amount of cesium fluoride are described. A versatile route to the synthesis of substituted aryl difluoromethane derivatives (8h–l, 10m, 12n, o, 14p) and the reactivity of ...
