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
