In this report, a combined experimental and computational study is presented, which provides mechanistic understanding of the unprecedented oxidative coupling of NHCs at Cu. The presence of CuI–, CuII–, and CuIII–NHC complexes during the process is postulated, with the unusual Ccarbene–Ccarbene oxidative coupling reaction occurring under extremely mild reaction conditions. This process may represent a novel pathway for the decomposition of Cu–NHC complexes.
