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 Bi2 (SO4) 3–TMSCl at room temperature.
