  摘要：

  An improved synthesis of the title ligand MBPA-H has made its complex chemistry accessible. With diethyl zinc it forms the reactive ethyl complex (MBPA)Zn-C2H5 (1) whose reaction with phenol leads to (MBPA)Zn-OC6H5 (2). With zinc nitrate the labile compound (MBPA)Zn-ONO2 (3) is formed which in turn is converted with thiophenolate into (MBPA)Zn-SC6H5 (4). Structure determinations of 2 and 3 have confirmed severely deformed trigonal-bipyramidal coordinations of the zinc atom whose ligation patterns correspond to those in some hydrolytic zinc enzymes.

  Reaction of the tetradentate ligand N-(2-hydroxybenzyl)-N,N-bis(2-pyridylmethyl)amine (L–OH) with MoO2Cl2 in methanol in the presence of NaOMe and PF6− results in the formation of [MoO2(L–O)]PF6. Similarly, the reaction of N-(2-mercaptobenzyl)-N,N-bis(2-pyridylmethyl)amine (L–SH) with MoO2(acac)2 leads to the formation of [MoO2(L–S)]+. The dioxo-molybdenum complex [MoO2(L–O)]+ reacts with phosphines in methanol to afford phosphine oxides and an air-sensitive molybdenum complex, tentatively identified as [Mo(IV)O(L–O)(OCH3)]. The latter complex is capable of reducing biological oxygen donors such as DMSO or nitrate, thereby mimicking the activity of DMSO reductase and nitrate reductase. Reaction of [MoO2(L–O)]PF6 with PPh3 in other solvents than methanol leads to the formation of the Mo(V) dimer [(L–O)OMo(μ-O)MoO(L–O)](PF6)2. The crystal structures of [MoO2(L–O)]PF6 and the μ-oxo bridged dimer are presented.

  四齿配体N-(2-羟基苄基)-N,N-bis(2-吡啶甲基)胺(L–OH)与 Cl2在甲醇中，在NaOMe和PF6−的存在下反应，形成[ (L–O)]PF6。类似地，N-(2-巯基苄基)-N,N-bis(2-吡啶甲基)胺(L–SH)与MoO2(acac)2的反应生成[ (L–S)]⁺。二氧茂铝复合物[ (L–O)]⁺在甲醇中与磷烯反应，生成磷烯氧化物和一个对空气敏感的铝复合物，暂时鉴定为[Mo(IV)O(L–O)(OCH3)]。后者复合物能够还原生物氧给体，如DMSO或硝酸盐，从而模拟DMSO还原酶和硝酸盐还原酶的活性。[ (L–O)]PF6与PPh3在不同于甲醇的溶剂中反应形成Mo(V)二聚体[(L–O)OMo(μ-O)MoO(L–O)](PF6)2。提供了[ (L–O)]PF6和μ-氧桥连二聚体的晶体结构。

  inexpensive catalysts is essential for photocatalytic CO2 reduction. Homogeneous molecular catalysts, possessing definite crystal structures, are desirable to study the relationship between catalytic performance and coordination microenvironment around catalytic center. In this report, we elaborately developed three Co(II)-based molecular catalysts with different coordination microenvironments for CO2 reduction

  创造有效且廉价的催化剂对于光催化CO 2还原至关重要。均质分子催化剂具有确定的晶体结构，适合研究催化性能与催化中心周围配位微环境之间的关系。在本报告中，我们精心开发了三种具有不同配位微环境的CO 2还原Co(II)基分子催化剂，分别命名为[CoN 3 O]ClO 4、[CoN 4 ]ClO 4和[CoN 3 S]ClO 4，分别。最优的[CoN 3 O]ClO 4光催化剂光催化还原CO 2的最大TON为5652 ，分别是[CoN 4 ]ClO 4和[CoN 3 S]ClO 4的1.28和1.65倍。L 1 ( N , N-双(2-吡啶甲基)-N- ( 2-羟基苄基)胺)中氧的高电负性为Co(II)催化中心提供了低还原电位和更稳定的*COOH中间体，促进CO 2到CO的转化并解释[CoN 3 O]ClO 4的高光催化活性。这项工作为研究人员开发光催化CO 2还原催化剂提供了新的见解。

  We report the first example of a sulfinato Fe(III) complex acting as a highly active electrocatalyst for proton reduction. The sulfinate binds to the metal through oxygen, resulting in a seven-membered chelate ring that is likely hemilabile during catalysis. Proton reduction occurs at -1.57 V versus Fc/Fc(+) in CH3CN with an i(c)/i(p) = 13 in CH3CN (k(obs) = 3300 s(-1)) and an overpotential of 800 mV. The catalysis is first order with respect to [catalyst] and second order with respect to [trifluoracetic acid]. An 11% increase in catalytic activity is observed in the presence of water, suggesting that sulfinate moieties are viable functional groups for aqueous proton reduction catalysts.
