Abstract

Abstract: 2, 2, 2-Trifluoro-1-(N, N-dimethylaminophenyl) ethanols were easily formed in excellent yields by electrophilic substitution between N, N-dimethylanilines 1a, b and trifluoroacetaldehyde ethyl hemiacetal (TFAE). The corresponding substitution of phenols 2a- e to prepare 2, 2, 2-trifluoro-1-(hydroxyphenyl) ethanols, however, occurred only in the presence of catalytic amounts of anhydrous potassium carbonate.
