1,2,3-triazole auxiliary directing group. Good to excellent yields were achieved with O2 as terminal oxidant. Other bidentate directing groups, such as 8-aminoquinoline, gave poor reactivity under this aerobic condition, highlighting the unique reactivity of triazole in promoting C–H activation.
使用1,2,3-三唑辅助导向基团可实现对苯基乙酸衍生物的实际邻区CHH烯烃聚合。用O 2作为末端氧化剂可达到良好至极好的产率。在该有氧条件下,其他双齿引导基团(例如8-氨基喹啉)的反应性较差,从而突出了三唑在促进C–H活化方面的独特反应性。
