Ultrasound promoted green synthesis of benzofuran substituted thiazolo[3,2-b][1,2,4]triazoles
A highly efficient, eco-friendly and one-pot synthesis of benzofuran substituted thiazolo[3,2-b][1,2,4]triazoles was developed involving the reaction of 2-acetyl benzofurans and 5-mercapto-3-(4-chlorophenyl)-1,2,4triazole in the presence of molecular iodine under ultrasonic conditions to give 5-(ben...
