A tandem and convergent approach to various N-, O-, or S-containing azoles has been developed by exploiting the thiophilic property of copper(I) iodide used in a catalytic quantity. The present protocol gives access to amino-substituted tetrazoles, triazoles, oxadiazoles and thiadiazoles via oxidative desulfurization of their respective precursors followed by inter- or intramolecular attack of suitable

Mononuclear Ni(II) and dinuclear Cd(II) complexes of 4-phenyl-2H-1,2,4-triazole-3-thione and Mn(II) catalyzed disulphide bond formation in 3,3′-dithio bis (4-phenyl-1,2,4-triazole): Syntheses, structural characterization, thermal analysis and DFT calculation
GRAPHICAL ABSTRACT Abstract Two series of thiosemicarbazide derivatives and three series of s-triazolederivatives have been synthesized. All of these compounds were tested for their in vitro antibacterial activity against Gram-positive and Gram-negative bacterial strains. Among tested thiosemicarbazide derivatives, the best bioactivity was detected for two 1-formylthiosemicarbazides with 3-/4-tolyl
