摘要：
A silver-catalyzed regioselective [3 + 2] cycloaddition reaction of PhSO2CF2CHN2 with aryl diazonium salts is described. This protocol enables the straightforward construction of a novel class of difluoromethylated tetrazoles under mild conditions, tolerates a broad spectrum of functionalities, and is applicable to one-pot operation from commercially available aniline derivatives. The synthetic merit of this method is further demonstrated by the facile preparation of versatile difluoromethylated azoles, including a valuable HCF2-analogue of P2X3 receptor antagonist.
