Abstract

A set of electrophilic 2-(trifluoroacetyl)-1,3-azoles demonstrated­ excellent activity in the C-oxyalkylation of pyrrole, furan, thiophene, 1,3-thiazole, and 1,2-oxazole derivatives. The reaction conditions and the yields of the corresponding trifluoromethyl-substituted alcohols depend strongly on both the electronic and steric nature of the 1,3-azole unit.
