Abstract
Abstract 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.
