Complexing Behaviour of 2H-1,2,4-Triazole-3-thiol Complexes of Co(II), Ni(II), Cu(II), Ru(II), Rh(III), Pd(II), Pt(II), and Au(I) [PDF]

Bulletin of the Chemical Society of Japan, 1978
Abstract Complexes of Co(II), Ni(II), Cu(II), Ru(II), Rh(III), Pd(II), Pt(II), and Au(I) with 2H-1,2,4-triazole3-thiol have been prepared. Probable structures have been proposed for the complexes on the basis of visible and infrared spectra, magnetic susceptibility, and chemical analysis.

AU(III) AND CU(II) CATALYST FOR OXIDATION OF AROMATIC AND CYCLIC HYDROCARBON BY CERIUM (IV) IN ACIDIC MEDIUM UNDER MICROWAVE IRRADIATION

Green Chemistry & Technology Letters, 2016
The addition of traces of Au(III) chloride with Ce(IV) sulphate (catalyst: substrate ratio (1: 80 to 1: 300)) and in case of  Cu(II) sulphate with Ce(IV) sulphate(catalyst: substrate ratio (1: 60 to 1: 250)) in solution phase under microwave irradiation resulted in good to excellent yields of corresponding to phenol, quinone and carbonyl compounds.

Synthesis and Biological Study of New Cu(II) and Au(III) Com-Plexes of 2,4-Dithiouracil and Its Derivatives

The goal of this study is to synthesize, determine the structure, and examine the antimicrobial properties of novel metal complexes of 2,4-dithiouracil and its derivatives. These complexes were obtained by mixing aqueous solutions of the corresponding metal salts with the ligand dissolved in DMSO and aqueous NaOH, using a metal-to-ligand ratio of 1:4:2.
