A fast and efficient method has been developed for the synthesis of triarylmethanes catalyzed by p-TsOH under microwave irradiation. The reactions of different aryl aldehydes carrying activated and deactivated groups with N,N-dimethylaniline in the presence of a catalytic amount of p-TsOH produced the corresponding triarylmethanes in good to excellent yields.
