A novel synthetic utility of NaICl2 for the preparation of bis(4-dimethaminophenyl)arylmethanes and bis(4-dimethaminophenyl)alkanes is described. In the presence of an aqueous solution of NaICl2, the reaction of arenes with aromatic aldehydes gives corresponding triarylmethane derivatives regioselectively in moderate to good yields. The method is also useful for the preparation of diarylalkane derivatives by using aliphatic aldehydes. Supplemental materials are available for this article.

A facile and efficient synthesis of an array of triarylmethanes by the Baeyer condensation of different arylaldehydes carrying activated and deactivated groups and N,N-dimethyIaniline using a catalytic amount of ZrOCI2 under solvent-free microwave irradiation conditions is described. Further, the catalytic activity of ZrOCI2 is compared with traditional Lewis acid catalysts and found that this synthetic method has the advantages of excellent yields (70-96%), shorter reaction time (few minutes) and solvent-free conditions.
