A broadly applicable rhodium-catalyzed direct ortho-arylation of anilines with (hetero)aryl halides based on readily available aminophosphines as traceless directing groups is reported. The ortho-arylated anilines could be obtained in high yields, without any competing diarylation and with full regioselectivity. The catalytic cycle was elucidated by DFT and supporting experiments.
