title: Catalytic selective bis-arylation of imines with anisole, phenol, thioanisole and analogues.
abstract: The first highly efficient double Friedel-Crafts reaction of N-tosyl imines with anisole, phenol, thioanisole and analogues has been developed to produce the corresponding symmetric diarylmethanes and triarylmethanes with high regioselectivity in the presence of a catalytic amount of Bi(2)(SO(4))(3)-TMSCl at room temperature.
