Five mononuclear complexes of Mn(II), Co(II), Ni(II), Cu(II), and Zn(II) with the Schiff base N-(2-hydroxyphenyl) 2-hydroxy-5-bromobenzaldimine were synthesized under microwave irradiation. The microwave irradiation method was found remarkably successful

A series of new mononuclear heteroleptic derivatives of aluminum(III), {[(CH3COCHCOCH3)AlL] (1 and 4)}, {[(C6H5COCHCOC6H5)AlL] (2, 5, and 7)}, and {[(C9H6NO)AlL] (3 and 6)}, have been synthesized by reacting Al(OPri)3 with tridentate Schiff base H2Lx (H2L1?=?C13H10BrNO2; H2L2?=?C14H13NO3; H2L3?=?C17H13NO2) and β-diketone/8-hydroxyquinoline (β-diketone?=?acetylacetone/dibenzoylmethane) in 1 : 1 : 1 stoichiometry using anhydrous benzene and ethanol. All the complexes were characterized by elemental analysis, FTIR, and NMR (1H and 13C) spectral studies. Molecular structures obtained from single-crystal XRD of aqua 1 (1a) and DMSO coordinated 2 (2a) authenticate their existence. Further, nanostructured α-alumina was synthesized from 1 by well-established sol–gel method and was characterized by powder XRD, TEM, and EDX analyses.

A series of new hepta-coordinated heteroleptic derivatives of zirconium(IV) of the types [(CH3COCHCOCH3)2ZrL] (1, 3, 5 and 7) and [(C6H5COCHCOC6H5)2ZrL] (2, 4, 6 and 8) (L?=?a dianionic [ONO]-tridentate ancillary ligand) was synthesized quantitatively by reacting Zr(OPri)4·PriOH with the tridentate Schiff's base ligands H2Lx(H2L1?=?C13H11NO2; H2L2?=?C13H10BrNO2; H2L3?=?C14H13NO3; H2L4?=?C17H13NO2) and β-diketones (acetylacetone/dibenzoylmethane) in a 1:1:2 stoichiometry using dry benzene and ethanol as solvents. All these newly synthesized solid derivatives were fairly soluble in common organic solvents. They were characterized by elemental analyses, FTIR and NMR (1H and13C) spectral studies. Single crystal XRD data of complexes 1, 2, 3 and 5 indicated the hepta-coordination and monomeric nature of these complexes. Furthermore, all these derivatives were tested for the ring opening polymerization of ε-caprolactone. The dibenzoylmethane derivatives were inactive in polymerizing ε-caprolactone unlike the acetylacetonate complexes. The molecular weight and polydispersity index values of polycaprolactone were obtained by GPC analysis. Kinetic studies for the rate of polymerization of ε-caprolactone by these catalytically active zirconium(IV) complexes authenticated the first order dependence of the polymerization rate on the monomer concentration. Among these, complex 3, with an electronegative bromine atom on the Schiff's base moiety, exhibited the best catalytic activity with a conversion of >95% in 2?h.
