An efficient approach to the synthesis of symmetrical N,N'-alkylidine bisamides from various aldehydes and amides in the presence of silica supported perchloric acid (HClO4-SiO2) has been described. The advantages of this method are easy work-up, short reaction times, excellent yields and the catalyst exhibited remarkable reusable activity.
Key words: HClO4-SiO2; aldehyde; amide; bisamide
