Palladium‐Catalyzed Direct Diarylation of 2‐Benzyl‐1,2,3‐triazole: a Simple Access to 4‐Aryl‐ or 4,5‐Diaryl‐2‐benzyl‐1,2,3‐triazoles and Phenanthro[9,10‐
<i>d</i>
][1,2,3]triazoles
Conditions for the direct mono‐ or di‐arylation of 2‐benzyl‐1,2,3‐triazole using phosphine‐free Pd(OAc)2 catalyst are described. This C−H arylation method was applied to the easy synthesis of π‐extended phenanthro[9,10‐d][1,2,3]triazoles.
描述了使用无膦的Pd(OAc)2催化剂直接进行2-苄基1,2,3-三唑的单芳基或二芳基化的条件。这种CH芳基化方法已应用于π扩展菲[9,10- d ] [1,2,3]三唑的简单合成。
