• Nickel-catalyzed one-pot synthesis of biaryls from phenols and arylboronic acids via C–O activation using TCT reagent

  日期：2015.4

  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。
