An efficient route for the synthesis of 2,4-disubstituted 1,2,3-triazoles by the regioselective direct arylation of 2-aryl-1,2,3-triazole N-oxides with Ar–X [X = Br, I and B(OH)2] is demonstrated. The reaction proceeds through Pd-catalyzed C–H bond activation, and the influence of the aryl halides on the reactivity is investigated.
通过 2-芳基-1,2,3-三唑 N-氧化物与 Ar-X [X = Br, I 和B(OH)2]进行说明。该反应通过 Pd 催化的 C-H 键活化进行,并研究了芳基卤化物对反应性的影响。
