A simple and efficient selective diacetoxylation of 1,4-disubstituted 1,2,3-triazoles by Pd-catalyzed C–H bond activation is described. PhI(OAc) 2 was used as an acetyloxy source to convert aromatic sp 2 C–H bonds into C–O bonds with high selectivity by employing a 1,2,3-triazole ring as an elegant directing group. A range of 1,2,3-triazoles bearing two acetyloxy groups can be readily synthesized by the reaction.

通过钯催化的 C-H 活化选择性双乙酰氧基化双取代 1,2,3-三唑

描述了通过 Pd 催化的 C-H 键活化对 1,4-二取代的 1,2,3-三唑进行简单有效的选择性二乙酰氧基化。PhI(OAc) 2 被用作乙酰氧基源,通过采用 1,2,3-三唑环作为优雅的导向基团,将芳香 sp 2 C-H 键以高选择性转化为 C-O 键。通过该反应可以很容易地合成一系列带有两个乙酰氧基的 1,2,3-三唑。
