    摘要:
    在Diels-Alder反应中,四个氟化的对苯醌(2)与Dane的二烯(1)反应,并对形成的氟化D-类固醇进行了表征。产品的数量,其立体化学和稳定性取决于相应的氟化对苯醌的氟取代模式。如果对苯醌(2)包含未氟化的双键,则该键与二烯1的反应更快,选择性地产生内产物。相反,[4 + 2]环加成有2,6-二氟(2c)和2,3,5,6-四氟苯醌(2d)给出了具有外向取向的产品羰 最好是一部分。

    摘要:
    The mechanism of the oxidation of mixtures of 2,6-dimethylaniline (1), N,N-dimethylaniline (2), 2,6-diethylaniline (3), N,N-diethylaniline (4), N-methylaniline (5), 2,6-difluoroaniline (6), and 2,3,5,6-tetrafluoroaniline (7) with 4-aminophenol (8) by cerium(IV) ions in aqueous perchloric acid has been investigated. The indoaniline salts [O=C6H4=N-C6H2(R-1)(2)NH(R-2)(2)]+ClO4- (R-1 = H, R-2 = CH3, C2H5 or vice versa) are formed as intermediates in the cross-coupling reaction; they undergo oxidation to imino-4-benzoquinone (9) and its corresponding derivatives by cerium(IV) ions in high yields. The mechanism of this process is discussed.

    complete trend reversal in their observed peroxidase kinetics and product yields. Although at pH 7.0 DHP-B had higher TCP oxidation activity than DHP-A as reported previously, as pH was lowered, DHP-A appeared to have a higher peroxidase activity than DHP-B. This is an unprecedented result. However, the fact that there are multiple processes contributing to both kinetics and yield of TCP oxidation complicates
    通过动力学测定、停止流光谱、共振拉曼光谱和高效液相色谱在 pH 5.0、6.0 和 7.0 下研究了脱卤过氧化物酶 A 和 B 中的 pH 依赖性过氧化物酶活性。在 pH 7.0 时,两种同工酶都遵循从使用稳态近似的三步反应方案派生的过氧化物酶乒乓动力学模型。然而,由于多个过程,在 pH < 6.0 和 [TCP] > 0.7 mM 时观察到与标准饱和行为的偏差:a) TCP 通过内部结合的自我抑制;b) 通过依赖于 pH 值和浓度的二次反应氧化产物;c) 在没有可氧化底物的情况下形成称为化合物 RH 的无活性物质。尽管 DHP-A 和 DHP-B 仅相差 5 个氨基酸,他们在观察到的过氧化物酶动力学和产物产量方面表现出完全的趋势逆转。尽管如前所述,在 pH 7.0 时,DHP-B 的 TCP 氧化活性高于 DHP-A,但随着 pH 值降低,DHP-A 似乎具有比 DHP-B 更高的过氧化
