  electron microscopy (FESEM) analyses. From the satisfactory results obtained from the reduction of nitrogen, this catalytic system is used for a one-pot protocol containing a reduction-Schiff base concentration of diverse nitroarenes. It was corroborated with the heterogeneous catalytic experiments on the one-pot tandem synthesis of imines from nitroarenes and aldehydes. Finally, the novel Ni-Fe3O4@Pectin~PPA ~ Piconal

  在这项工作中，首先合成了一种称为 Ni-Fe 3 O 4 @Pectin~PPA~Piconal的多相纳米催化剂，并将其作为含有镍官能团的双功能催化剂进行研究。另一方面，这种 Ni-Fe 3 O 4 @Pectin~PPA ~ Piconal 催化剂在水性溶剂中在环境温度下对与硼氢化钠的硝基芳烃还原反应显示出非常有效的性能，其中 NaBH 4被认为是还原剂。这是一种新型磁性催化剂，已通过多种方法批准，包括傅里叶变换红外光谱 (FT-IR)、X 射线粉末衍射 (XRD)、动态光散射 (DLS)、透射电子显微镜 (TEM)、振动样品磁力计 (VSM)、电感耦合等离子体 (ICP)、能量色散 X 射线光谱 (EDX) 和场发射扫描电子显微镜 (FESEM) 分析。根据从氮还原中获得的令人满意的结果，该催化系统用于包含多种硝基芳烃的还原希夫碱浓度的一锅法。硝基芳烃和醛类一锅串联合成亚胺的多相催化实验证实了这一点。最后，新型Ni-Fe

  The present work deals with the imidorhenium(V) complexes of type [ReCl3(NC6H4Y-p)(L)], with Y = OCH3(1d), CH3(1c), H(1b), Cl(1a) where L is the pyridylimine Schiff base ligand obtained from facile condensation of pyridine-2-carboxaldehyde and p-phenylenediamine. Structural authentication of one representative (1d) reveals meridional disposition of three Cl atoms around the metal center in a distorted octahedral ReCl3N3 coordination environment. Re-N-pyridine bond lying trans to Re NC6H4Y-p motif is lengthened by similar to 0.2 angstrom compared to Re-N-imine bond and is attributed to trans influence of imide nitrogen. The complexes, I are reactive towards dilute aqueous nitric acid furnishing amide bound hexavalent rhenium complexes, 2. Six lines EPR spectra have been recorded for 2 in solution phase at ambient condition (g(iso) similar to 1.945, A(av) similar to 493 G) and magnetic susceptibility measurement indicates strong orbital coupling consistent with one electron paramagnetic nature (similar to 1.45 mu(B)). Re-VI/Re-V responses for 1 appear at higher potential (similar to 0.95 V) that those observed for 2 (similar to 0.12 V). Type 2 complexes are reduced (low Re-VI/Re-V reduction potential, +0.15 V) by N2H5+ and NH3OH+ species under mild condition to regenerate 1. The reduction with N2H5+ is nearly five times faster than NH3OH+. Rate study suggests an associative pathway (Delta H-not equal = 11.61 kcal mol(-1), Delta S-not equal = -31.22 eu using N2H5+ and Delta H-not equal = 10.74 kcal mol(-1), Delta S-not equal = -37.30 eu using NH3OH+) for amide -> imine transformation. No such analogous amide -> imine conversion has yet been achieved in metal free environment, accentuating the exclusive electronic role of variable metal valence. Further, the oxo complex, 6 does not exhibit intramolecular ligand oxidation suggesting decisive electronic role of the coligands (oxo/arylimido) in stabilizing higher metal valence.

  A pyridyl-amine Schiff-base compound (L = N-(2-pyridylmethylene)benzene-1,4-diamine) reacted with several metal salts (Cd(NO3)(2)center dot 4(H2O), Ni(NO3)(2)center dot 6(H2O), Co(NO3)(2)center dot 6(H2O), CoCl2 center dot 6(H2O), Co(ClO4)(2)center dot 6(H2O)) to give molecular complexes: [M(L)(2)(NO3)]center dot(NO3) (M = Cd (1), Ni (2), Co (3)), cis-[Co(L)(2)Cl-2] (C6H6) (4), and [Co(L)(3)]center dot(ClO4)(2)center dot(CH3CN)(2)center dot(H2O) (5). Complexes 1-3, whose starting compounds possess NO3- anions, were isostructural octahedral complexes. In complexes 3-5, whose starting compounds have the same metal but different anions, the anions in the products exhibited different coordination modes depending on the identity of the metal. In all complexes, the amine end of the ligand (L) remains uncoordinated. The thermal behavior of the complexes is also described. (C) 2018 Elsevier Ltd. All rights reserved.
