    一氧化碳脱氢酶将氰酸盐还原为氰化物
    摘要:
    一氧化碳脱氢酶(CODH)的生物催化功能由于其还原CO 2的能力而具有很高的环境相关性。尽管在过去几十年中对CODH进行了大量研究,但其催化机理尚未完全明了。在本组合光谱和理论研究中,我们报告第一证据为氰酸酯(NCO - )氰化物(CN - )的C-簇减少。该加合物保持结合到催化中心,以形成所谓的CN - -inhibited状态。值得注意的是,这种转化不会发生在氢羧化羧化酶CODH酶(CODHII Ch)的晶体中,如缺乏相应的CN-所表明的那样。拉伸模式。NCO的转化- ,其也充当两电子还原的C的抑制剂RED2 CODH的状态,从而能模仿CO 2周转和CODH的详细催化机理的阐明打开新的前景。

    Abstract The water substitution reactions of the monocation Co(III)(H 2 O) 2 (salen) + [salen = N,N′-ethylene-bis(salicylideneiminate)] were studied in aqueous solution. The nucleophiles used were pyridine, thiourea, morpholine, aniline, imidazole, NCO − , HSO 3 − , S 2 O 3 2− . The kinetics of mono-substitution reactions were found to be very rapid, with second order rate constants nearly independent

  • Gas-phase reactions of the hydroperoxide and peroxyformate anions

    The flowing afterglow technique has been used to study the reactions of HO2and HC3 in the gas phase. The hydroperoxide ion reacts slowly with CO to form HO, and oxidizes CO2, OCS, CS2, NO, SO2, CH3NCO, and CH3NCS in fast reactions to form CO3, CO2S, COS2, NO2, SO3, CH3NCO2, and CH3NCOS, respectively. Reactions of HO2 with certain amides and esters provide synthetic routes for a number of interesting peracyl anions. One of these, the peroxyformate ion, HCO3, reacts with CO and NO in slow oxidation reactions to form the formate ion HCO2. It also forms HCO2 upon reaction with acetone and pivalaldehyde, perhaps by Baeyer–Villiger oxidation.
