The symmetrical triarylmethanes were also obtained from diarylamines and suitable nucleophiles via simultaneous cleavage of sp3 C-N bond and elimination of 1,3,5-trimethoxybenzene.enAreneAza-Friedel-Crafts reactionDiarylaminesHeterobimetallic catalysisIndolesIridiumN-Sulfonyl aldimineTinTriarylmethanesArticle
