Asymmetric arylation of aldimines catalyzed by heterogeneous chiral rhodium nanoparticles proceeded in aqueous media to afford chiral (diarylmethyl)amines in high yields with outstanding enantioselectivities. This heterogeneous catalyst system exhibited very high turnover numbers. The reusability of the catalyst was also demonstrated.
