One‐pot synthesis of ferrocenyl ligand, 1,1′‐bis[1,5‐methyl‐4H‐(1,3,4)‐thiadiazolo(2,3‐c)(1,2,4)triazin‐4‐one]ferrocene was prepared from the reaction of 1,1′‐diacetylferrocene with 4‐amino‐2,3‐dihydro‐6‐methyl‐3‐thioxo[1,2,4]triazin‐5(4H)one. The ligand, L, forms 1:1 complexes with Mn(II), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) in good yield. Characterization of the ligand and its complexes was carried out using IR, 1H NMR, magnetic susceptibility as well as elemental analysis. Biocidal activity of the ligand and its complexes were determined against the standard fungal strains of Aspergillus niger, Cladosporium herbarum and Fusarium moniliforme using the paper disc diffusion method; and against bacterial strains of Escherichia coli and Staphylococcus aureus using viable cell counting technique. The results indicated that the complexes are biologically more active than the free ligand. The biocidal activity depends on the metal ion, concentration as well as the tested fungi and bacteria.

A new ferrocenyl ligand, 1,1′‐bis[1‐methyl‐5‐phenyl‐4H‐(1,3,4)‐thiadiazolo(2,3‐c)(1,2,4)triazin‐4‐one]ferrocene was prepared from the reaction of 1,1′‐diacetylferrocene with 4‐amino‐2,3‐dihydro‐6‐phenyl‐3‐thioxo[1,2,4]triazin‐5(4H)one. The ligand, L, forms 1:1 complexes with Mn(II), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) in good yield. Characterization of the ligand and its complexes was carried out using IR, 1H NMR, magnetic susceptibility as well as elemental analysis. Biological activity of the ligand and its complexes were carried out against Aspergillus niger, Cladosporium herbirum and Fusarium moniliformae using filter paper discs; and against bacterial strains of Escherichia coli, Staphylococcus aureus using viable cell counting technique. The results indicated that the ligand is biologically active whereas the complexes are more active than the ligand. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

The heat capacities of acetylferrocene, 1,1′-diacetylferrocene, and 1,1′-diethylferrocene were investigated by low-temperature
adiabatic calorimetry in the temperature range from 5 to 300 K and their thermodynamic functions were calculated. The enthalpies
of combustion of the substances were determined by calorimetry of combustion, and the thermodynamic functions of their formation
were calculated by quantum chemistry methods. Inter- and intramolecular interactions of the ferrocene derivatives were also
studied by the methods of molecular mechanics and molecular dynamics.

A new ferrocenyl ligand was prepared from the condensation of 1,1′‐diacetylferrocene dihydrazone with 2‐thiophenealdehyde. The ligand, 1,1′‐bis[(2‐thienylmethylidene)hydrazono‐1‐ethyl]ferrocene, forms 1:1 complexes with cobalt(II), nickel(II), copper(II) and zinc(II) in good yield. Characterization of the ligand and complexes was carried out using IR, 1H NMR, electronic absorption and elemental analysis. Biological activity of the ligand and its complexes was assessed against Bacillus subtilis (+ve), Staphylococcus aureus (+ve), Candida albicans (yeast), Esherichia coli (?ve), Salmonella typhi (?ve), Aspergillus niger (fungi), and Fusarium solani (fungi). The biological results indicated that the complexes prepared are more active than the ligand. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献
