HClO4-SiO2: An efficient reusable catalyst for the synthesis of 3,4,5-trisubstituted 1,2,4-triazoles under solvent-free conditions
A series of 3,4,5-trisubstituted 1,2,4-triazoles have been synthesized from N3-substituted amidrazones and anhydrides using HClO 4-SiO2 at 80 °C under solvent-free conditions. The products were obtained in excellent yields
Efficient and regiospecific one-pot synthesis of substituted 1,2,4-triazoles
(Equation Presented) An efficient one-pot, three-component synthesis of substituted 1,2,4-triazoles has been developed, utilizing a wide range of substituted primary amines and acyl hydrazides.
