Synthesis and characterisation of some coumarin-1,2,4-triazol-3-thioether hybrid molecules

Abstract

A new series of N'-{[(4-methyl/phenyl-5-phenyl-4H-1,2,4-triazol-3-yl) thio] acetyl}-2-oxo-2H-chromene-3-carbohydrazides was synthesised via the reaction of 2-[(4-methyl/phenyl-5-phenyl-4H-1,2,4-triazol-3-yl) thio] acetohydrazides and 3-(1H-benzotriazol-1-ylcarbonyl)-2H-chromen-2- ones in good yields.
