A New Method for Regioselective Introduction of Trifluoromethyl Groups into Heteroarenes; Part2. Nucleophilic Substitution of 5-Fluoro-4- trifluoromethyl-1,3-azoles 5-Fluoro-4-trifluoromethyl-1,3-azoles are readily susceptible to nucleophilic displacement reactions at C-5. With binucleophiles, the reactioncan be used for linking trifluoromethyl-substituted 1,3-azoles to aromatic, heteroaromatic, and heterocyclic systems, linearly or angularly,directly or across various bridging groups respectively.
