Gold‐catalyzedoxidativecross‐coupling reactions of two distinct arenes with one gold carbene furnish triarylmethane products. Notably, competitive homo‐coupling reactions are efficiently suppressed with a phosphoric acid as co‐catalyst (10 mol%) in THF. These cross‐coupling reactions have a wide scope of applicable substrates, with respect to indoles, arylamines, and α‐aryl diazo cyanides or esters
