Abstract: 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?°C under Pd-free conditions.
