Triarylmethane derivatives and their syntheses are of great interest owing to their broad applicability in areas from textiles to medicine. In this study, the green solvent [ChCl][ZnCl2] synergistically promoted Baeyer condensation between benzaldehyde and N-substituted aniline to efficiently synthesize triarylmethane derivatives with high para-selectivity. The employed deep eutectic solvent acted as both a catalyst and green reaction medium for the reaction. Moreover, the deep eutectic solvent was reused several times in this procedure without significant loss of activity.
