Four methoxy substitute salicylidene thiosemicarbazones were synthesized. The reaction of both thione and thioalkylated thiosemicarbazones with PdCl2 in ethanol yields ONS-coordinated chelate complexes with general formula [Pd(L)Cl]. The structures of eight compounds were characterized by using anal. and spectroscopic methods. Electrochem. of the Pd(II) complexes was studied using cyclic voltammetric technique. The CVs of the complexes were quite complicate because of some oxidative responses of the ligands which proceed by forming conjugated -N:CH-, -HC:CH- and -N:CH-HC:CH- groups. Two cathodic responses attributed to one electron reduction of Pd(II)/(I) and Pd(I)/(0) were observed for the central ion coordinated with S atom of H3C-S- group whereas only one reduction peak appeared when the Pd(II) coordinated with S atom of >C:S group of thiosemicarbazone ligand. The latter also showed an addnl. anodic response assigned to Pd(II)/(III) oxidation Thermogravimetric anal. (TGA) technique was used to investigate and compare the thermal properties of the ligands and their metal complexes. In vitro antimicrobial activity of thiosemicarbazones and their complexes was evaluated against four Gram-neg. bacteria, three Gram-pos. bacteria, and antifungal activity against three fungi. After reading the article, we found that the author used 2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3Electric Literature of C8H8O3)
2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3) is the main component of root bark essential oil of Periploca sepium Bunge. It is a potential tyrosinase inhibitor present in African medicinal plants. 2-Hydroxy-4-methoxybenzaldehyde was used in the synthesis of Schiff base ligand.Electric Literature of C8H8O3
