A set of highly electrophilic 2-trifluoroacetyl-1,3-heterazoles demonstrated excellent activity in the C-hydroxyalkylation of 1H-indole. The reaction conditions and yields of the corresponding trifluoromethyl-substituted alcohols depend strongly on the electron-withdrawing nature of the 1,3-heterazole unit.
