Chitosan supported Zn(II) mixed ligand complexes have been synthesized and characterized by FT-IR, UV–Vis, TGA, XRD, FESEM, EDX, AAS and Elemental Analysis. These complexes have been found to be efficient and recyclable heterogeneous catalysts for the one-pot synthesis of amides via Beckmann rearrangement. All three complexes can be easily filtered out from the reaction medium and reused up to five times without significant loss of catalytic activity. The reported protocol is economical and novel in the sense that amides can be easily synthesized in only one-step. All products were obtained as white to off-white crystalline solids and fully characterized by 1H NMR, FT-IR and Mass Spectra.

Abstract The Chitosan anchored Cu(II) Schiff base complexes (C1-C3) have been synthesized and characterized by FTIR, UV, FE-SEM, EDAX, TGA, AAS and elemental analysis. These complexes have been found to be efficient and recyclable heterogeneous catalysts for the Chan-Lam C-N coupling reaction of various aromatic/aliphatic amines with arylboronic acid under mild reaction conditions. These complexes can be easily filtered out from the reaction medium and reused up to five times without significant loss of catalytic activity.

, p. 116 - 125 (2014/03/21)
Six metal complexes were synthesized from Cd (II), Mn (II) and Zn (II) chloride and ligands 2-((3- nitrophenylimino)methyl)phenol (HL1) and 2-((4-nitrophenylimino)methyl)phenol (HL2) in 1:2 M ratio. Microanalytical data, UV-Visible spectral data, magnetic susceptibility, IR, 1HNMR, 13CNMR, mass and molar conductance measurements were used to characterize the structure of complexes. The complexes were found to be non electrolytic on the basis of molar conductance studies. The Schiff bases and their metal complexes had also been screened for their antinemic activity against root knot nematode, Meloidogyne incognita. Complexes have shown significant antinemic activity than their corresponding Schiff bases.

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.
