Abstract:A simple, efficient and environmentally benign protocol for the synthesis of methylenebisamides and carbinolamides in high yields from aromatic amides and formaldehyde in the presence of heterogeneous catalysts (Hβ and NaY zeolites) using water as a solvent is demonstrated. Moreover, the catalyst is recyclable and can be reused without significant loss in its catalytic activity.
