  Coordination of Schiff bases derived from pyrrole-2-carboxaldehyde and triamines to copper(II) and nickel(II) ions. Crystal structures of [Cu(C15H20N5)]NO3 and [Ni(C15H20N5)]ClO4

  摘要：

  The Schiff bases 1,9-bis(2-pyrrolyl)-2,5,8-triazanona-1,8-diene (H-2L1). 1,10-bis(2-pyrrolyl)-2,5,9-triazaundeca-1,9-diene (H-2L2), and 1,11-bis(2-pyrrolyl)-6-methyl-2,6,10-triazaundeca-1,10-diene (H-2L4) react with copper(II) nitrate or nickel(II) perchlorate in the presence of triethylamine to give new complexes [Cu(HL1,2,4)]NO3 and [Ni(HL1,2,4)]ClO4. The crystal structures of [Cu(HL2)]NO3 and [Ni(HL2)]CIO4 have been determined from single crystal diffractometer data and refined to final R factors of 5.09 and 5.3 %, respectively. Crystallographic data: [Cu(HL2)]NO3: monoclinic, P2(1)/c, a = 10.036(2), b = 14.500(2), c = 13.317(2) angstrom, beta = 108.14(1)-degrees, Z = 4, and d(c) = 11.427 Mg m-3; [Ni(HL2)]ClO4: monoclinic, P2(1)/n, a = 10.578(3), b = 13.953(3), c = 12.394(4) angstrom, beta = 93.78(2)-degrees, Z = 4, and d(c) = 1.549 Mg m-3. In both the structures the potentially pentadentate ligand (HL2)- acts as a tetradentate one leaving one pyrrole group uncoordinated. Interesting is the metal dependent sequence of the three chelate rings. While the Ni(II) ion coordinates the (HL2)- ligand to form a 5-5-6-membered ring system, the ring arrangement in the copper complex is of the 5-6-5 type.

  In this work, a copper Schiff base complex immobilized on silica‐coated Fe3O4 nanoparticles is synthesized, and studied as a highly efficient, recyclable, green and heterogeneous catalyst for the preparation of polysubstituted pyrroles under solvent‐free and mild conditions. This new catalyst was characterized by different techniques, such as Fourier transform infrared (FT‐IR), X‐ray powder diffraction

  Reaction of the bis-ligand-chelated samarium complex [Sin (Hbptd)(H(2)bptd)1 (1; H(3)bptd = (2-pyrroly1)-2,5,8-triazanon a-1,8-diene), in which a pyrrolyl ring is dangling and metal-free, with Ti(NMe2)(4) yielded the heterometallic complex [Sm(Hbptd)(THF) (bptd)Ti(NMe2)(2)] (2). Treatment of the H3bptd ligand with 1 equiv of Ti(NMe2)(4) gave the titanium amido complex [Ti(bptd)(NMe2)] (3). Complexes 2 and 2; were able to catalyze the hydroamination of phenylacetylene with 2,4-dichloroaniline and 4-methoxyaniline, and high regioselectivities were observed for the two amines. Both 1 and 2 were active catalysts for the ring-opening polymerization of epsilon-caprolactone. 2 showed higher activity for the polymerization reactions, due to a decrease in the coordination number of the samarium atom (from 9 in 1 to 8 in 2) by sharing its ligand with the titanium center.
