2 has been introduced to be an extremely efficient catalyst for the preparation of N,N’ -alkylidene bisamides from various aldehydes and amides under mild conditions. We synthesized this solid Lewis acid catalyst by the reaction of nano-SiO 2 and TiCl 4 . The processor was simple and environmentally benign with high to excellent yields. Our method has the advantages of high yields, simple methodology

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.
