Abstract

Efficient and Convenient Protocol for the Synthesis of 3,5-Disubstituted 1,2,4-Oxadiazoles Using HClO 4-SiO2 as a Heterogeneous Recyclable Catalyst. -The protocol uses amidoximes (I) and acid anhydrides (II) as starting materials and provides the corresponding products (III) in good to excellent yields. -(TADIKONDA, R.; NAKKA, M.; GAJULA, M.
