catalyzed three-component reaction of 2-(arylethynyl)anilines with arylaldehydes has been achieved, which leads to the generation of 3,3′-(arylmethylene)bis(1H-indoles) with good to excellent yields and high regioselectivity under transition-metal-free conditions. Four new C–C and C–N bonds were effectively formed in a one-pot procedure. Subsequent research on the reaction mechanism indicated that the
