In this study, the direct Nickel-catalyzed Suzuki–Miyaura coupling reaction of phenols and arylboronic acids via C–O bond activation using 2,4,6-trichloro-1,3,5-triazine (TCT) is described. Initially, phenols were reacted with TCT to give the corresponding 2,4,6-triaryloxy-1,3,5-triazine (TAT) products. Subsequently, arylboronic acid, base and Ni-catalyst were added to the generated aryl C–O electrophile
在这项研究中,描述了使用2,4,6-三氯-1,3,5-三嗪(TCT)通过C–O键活化的酚和芳基硼酸的直接镍催化Suzuki–Miyaura偶联反应。最初,苯酚与TCT反应,得到相应的2,4,6-三芳氧基-1,3,5-三嗪(TAT)产物。随后,将芳基硼酸,碱和Ni催化剂添加到生成的芳基C-O亲电试剂中,以获得最终的联芳基产物。这项研究代表了一种简单直接的方法,使用亚化学当量的TCT作为廉价且容易获得的C–O活化剂,从酚类化合物合成联芳基。
