Mechanochemical protocol has been exploited to accomplish the synthesis of imino derivatives from aromatic amines with acidic functionalities and different aromatic aldehydes in excellent to nearly quantitative yields. Presence of acidic groups in the aromatic amines has been found to have profound influence on the course of the reaction. The prepared imines were screened for in vitro antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical. Some of the prepared imino derivatives displayed good to moderate antioxidant property when compared with standard natural antioxidant (L-ascorbic acid).

Several cis-dioxomolybdenum(VI) complexes with Schiff bases-derived ligands were synthesized and fully characterized. The catalytic performances of these complexes were tested in the alcohol oxidation under solvent-free condition using H2O2 as oxidant giving high results. The influence of the oxygen, sulfur, and nitrogen atom within the coordination sphere around the molybdenum center was studied (S?>?N?>?O). From this study, we suggest that there exists a relationship between the electronegativity of the atom and the catalytic performance in alcohol oxidation.

Mixed ligand complexes of iron(III), [Fe(sb)2(py)Cl] 2H 2O (1-9) [where sbH = Schiff bases (derived from condensation of 2-aminopyridine (sapH), 2-aminophenol (saphH), o-toluidine (o-smabH), aminobenzene (sabH), p-toluidine (p-smabH), 3-nitroaniline (snabH), and anthranilic acid (saaH) with salicylaldehyde and substituted (mercapto-)benzimidazole (mbzH), {2-(o-hydroxyphenyl)}benzoxazole, (pboxH)], have been synthesized by the interactions of iron(III) chloride with corresponding ligands in 1 : 2 molar ratio in refluxing pyridine. These complexes have been characterized by elemental analyses, melting points, spectral, and magnetic studies. Powder X-ray diffraction studies of some representative complexes are also reported herein. The antibacterial and antifungal activities of the free ligands and their iron(III) complexes were found invitro. The complexes showed good antibacterial and antifungal effect to some bacteria and fungi. Two standard antibiotics (chloromphenicol and terbinafine) were used for comparison with these complexes.
