摘要：

CuI accompanyied by Cs2CO3 and TBAB was confirmed to be an efficient catalyst combination to promote an Ullmann coupling reaction. It facilitated 2-bromobenzamides to undergo a coupling reaction for the synthesis of symmetrical biaryldiamides in moderate yields at 120 degrees C under Pd-free conditions. [GRAPHICS] .
