Abstract
A highly efficient procedure for the preparation of N,N ′-alkylidenebisamides in the presence of nano-SnCl4.SiO2 as a catalysis described. N,N ′-alkylidenebisamides have been prepared via condensation reaction of various aldehydes and amides. All of the reactions proceeded in high yields and in moderately short reaction times.

Nano-SnCl4.SiO2 as a heterogeneous and reusable catalyst has been used for the synthesis of N,N ′-alkylidenebisamides via condensation of aldehydes and amides. The structures of products have been determined by FT-IR and 1H-NMR spectroscopy. Clean process, simple methodology and easy work-up are some advantages of this protocol.
