Coordination Chemistry of Polycyclic Thiosemicarbazones. I. Reactions of the Thiosemicarbazone from 9-anthraldehyde
نویسندگان
چکیده
The thiosemicarbazone of 9-anthraldehyde, (9-ATSC) and its group 12 metal complexes have been synthesized. The four compounds have been characterized by IR, electronic and NMR spectrometries, molar conductivity, melting points and elemental analysis. In all the complexes, the 9-ATSC coordinates through the sulfur and the azomethinic nitrogen. The zinc (II) complex shows a 1:2 metal to ligand stoichiometry while the mercury(II) and cadmium(II) complexes exhibit 1:1 metal-ligand composition. The compounds show moderate inhibitory activity against Bacillus cereus, Proteus vulgaris, Enterococcus faecalis, and Salmonella typhimurium. It was seen that the complexes were generally more active than the free ligand.

A novel thiosemicarbazone from 2-acetonaphthone (represented as acnTSC) has been synthesized and its basic coordination chemistry with zinc(II), cobalt(II), and copper(II) explored. The complexes were characterized by elemental analysis and various spectroscopic techniques and are best formulated as [M(acnTSC)(2)Cl(2)] with the metal likely in an octahedral environment. The anticancer activity ...

Some 2-iminothiazolidin-4-ones have been synthesized by the reaction of dialkyl acetylenedicarboxylates with thiosemicarbazones. The reaction was performed in the presence of 10 mol% of triphenylphosphine and tetrabutylammonium bromide as a phase transfer catalyst in water as a green solvent. All the synthesized compounds were characterized by their physical and spectral data.
