    名称:
    New Unsymmetrical Oxovanadium(IV) Complexes of Mixed‐Donor Amido and Oxo Ligands
    摘要:
    The novel, unsymmetrical, mixed-donor, tetradentate amido, and oxo complexes of V(IV) of the general formula VOLx were synthesized by a nontemplate method and characterized by physico-chemical methods. The ligands were prepared by a two-stage aldol condensation reaction in the molar ratio I : I of 2-hydroxybenzaldehyde, 2'-hydroxyacetophenone, or 2',4'-dihydroxyacetophenone and 1,2-diaminopropane of the general formula HA(x) (x = 1-3) as precursors. The tetradentate mixed donor ligands of the general formula H2Lx (x = 1-6) were obtained by condensation reaction of precursors with appropriate ketone or aldehyde. The synthesis of the ligand system, described here, is an efficient and easy method with the advantages of high yield, selectivity, and short reaction times. Only a brown polymeric form was obtained for VOL2 and green monomeric forms were obtained for VOLx, x = 1, 3-5, while in the presence of strong field ligands only monomeric forms were obtained. These observations suggest that monomeric forms of oxovanadium(IV) complexes exhibit a coordination number of five with N2O3 donor sets and the polymeric form exhibits a coordination number of six with N2O4 donor sets. Analytical data, H-1 NMR, IR, UV-VIS spectra, and elemental analyses confirm the nature of the products.

    可见光诱导的钒催化氧化木质素CC键裂解为醛
    摘要:
    木质素是地球上最大的芳烃载体,其解聚作用可提供增值的芳烃产品。木质素键中C–C键的直接裂解很重要,但是要获得低分子量的芳族单体却具有挑战性。在本文中,我们使用可见光下的钒催化剂,选择性裂解木质素模型中封闭的β-1和β-O-4互连中的C–C键,并通过氧化方案提取。可见光照射引发的底物和催化剂,从而进一步诱导选择性℃之间单电子转移α -C β键断裂和产生通过自由基中间体的最终芳族产物。利用这种光催化化学,木质素模型的反应和C的选择性α-C β键裂解物显著改善。更重要的是,该协议即使在室温下也能通过有机溶剂木质素的断裂而提供芳族单体,这表明在环境条件下木质素键的光催化C–C键裂解的潜力。
