Synthesis, Characterization, and Crystal Structures of Copper(II) and Zinc(II) Complexes Derived From the Tridentate Schiff Bases 2-[1-(pyridin-2-ylmethylimino) ethyl]phenol and (1-pyridin-2-ylethylidene)pyridin-2- ylmethylamine
A centrosymmetric phenolate oxygen bridged dinuclear copper(II) complex [Cu2(L1)2(N3)2] (1) and a mononuclear zinc(II) complex [Zn(L2)(NCS)2] (2), where HL1 = 2-[1-(pyridin-2-ylmethylimino)ethyl]phenol and L2 = (1-pyridin-2-ylethylidene)pyridin-2-ylmethylamine, were synthesized and structurally characterized by physicochemical methods and single-crystal X-ray diffraction. The Cu atom in (1) is five-coordinated
protocol for the regioselective hydroxylation of sp2 and sp3 C–H bonds using a directing group, stoichiometric amounts of Cu and H2O2. A wide array of aromatic ketones and aldehydes are oxidized in the carbonyl γ-position with remarkable yields. We also expanded this methodology to hydroxylate the β-position of alkylic ketones. Spectroscopic characterization, kinetics, and density functional theory calculations
与其他金属相比,将铜用于C–H键功能化的研究相对较少。在本文中,我们报告了使用导向基团,化学计量的Cu和H 2 O 2对sp 2和sp 3 C–H键的区域选择性羟基化的合成方案。各种各样的芳族酮和醛在羰基γ位被氧化,收率很高。我们还扩展了该方法以羟基化烷基酮的β-位。光谱表征,动力学和密度泛函理论计算都指向单核LCu II(OOH)物种的参与,该物种会氧化芳香族sp 2 通过协调的杂合O-O键裂解C-H键,并伴随对芳烃系统的亲电子攻击。
Catalytic efficacy of Schiff-base copper(II) complexes: Synthesis, X-ray structure and olefin oxidation
Three copper(II) Schiff-base complexes, [Cu(L-1)(H2O)](ClO4) (1), [Cu(L-2)] (2) and [Cu(L-3)] (3) have been synthesized and characterized [where HL1 = 1-(N-ortho-hydroxy-acetophenimine)-2-methyl-pyridine], H2L2 = N,N'-(2-hydroxy-propane-1,3-diyl)-bis-salicylideneimine and H2L3 = N,N'-(2,2-dimethyl-propane-1,3-diyl)-bis-salicylideneimine], The structure of complex 1 has been determined by single crystal X-ray diffraction analysis. In complex 1, the copper(II) ion is coordinated to one oxygen atom and two nitrogen atoms of the tridentate Schiff-base ligand, HL1. The fourth coordination site of the central metal ion is occupied by the oxygen atom from a water molecule. All the complexes exhibit high catalytic activity in the oxidation reactions of a variety of olefins with tert-butyl-hydroperoxide in acetonitrile. The catalytic efficacy of the copper(II) complexes towards olefin oxidation reactions has been studied in different solvent media. (C) 2008 Elsevier Ltd. All rights reserved.
