FLUORINATION OF AROMATIC α-HYDROXYESTERS WITH N,N-DIETHYL-1,1,2,3,3,3-HEXAFLUOROPROPANEAMINE

Watanabe, S.,Fujita, T.,Sakamoto, M.,Endo, H.,Kitazume, T.

, p. 187 - 192 (2007/10/02)

The reaction of N,N-diethyl-1,1,2,3,3,3-hexafluoropropaneamine (PPDA) with aromatic α-hydroxyesters exchanged F for OH and gave their corresponding fluorides.For example, ethyl 2-fluoro-2-(p-tolyl) acetate was obtained from the reaction of ethyl 2-hydroxy-2-(p-tolyl) actate with PPDA.
