The Ullmann cross-coupling reaction between 2-(2-bromophenyl)-4,5-diphenyl- 1H-imidazole and 2-bromobenzenethiol occurred to give 2,3-diaryldibenzo[b,f]imidazo[1,2-d] [1,4]thiazepines in good yields. Two new bonds of Csp2-N and Csp2-S were built under the same catalytic system of CuI/o-phen in the presence of K2CO3.

CuI通过C–N和C–S键Ullmann交叉偶联反应催化合成二苯并[ bf ]咪唑并[1,2- d ] [1,4]硫氮杂ze

发生2-(2-溴苯基)-4,5-二苯基-1H-咪唑与2-溴苯硫醇之间的乌尔曼交叉偶联反应,得到2,3-二芳基二苯并[ bf ]咪唑[1,2- d ] [1,4]噻氮平产量高。在K 2 CO 3存在下,在相同的CuI / o- phen催化体系下建立了Csp 2 -N和Csp 2 -S的两个新键。
