The title condensation provides the corresponding (1′-hydroxy-2′,2′,2′-trifluoroethyl)imidazoles in yields dependent on the electronic nature of the substituent: ortho-para directors promote the reaction while meta directors retard it strongly. 1-Alkylimidazoles gave only 2-adducts. 2-Substituted imidazoles yielded 4(5)-adducts together with small amounts of 4,5-bis-adducts. 4(5)-Substituted imidazoles
