摘要：

Acid-catalyzed electrophilic trifluoromethylation of nitriles in the presence of azoles leads to N-(trifluoromethyl)imine derivatives. The source of the trifluoromethyl group is a readily prepared and easy-to-handle hypervalent iodine(III) reagent (see scheme; HNTf2=bis(N- (trifluoromethanesulfonyl)imide). This Ritter-type reaction is astraightforward approach to N-(trifluoromethyl)imidoyl azoles, compounds otherwise very difficult to access. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
