    摘要:
    确定了氢化物从脂肪醇到乙腈中两个碳正离子(NAD(+)模型)的氢化物转移反应的二次动力学同位素效应。结果表明,氢化物转移是通过隧穿发生的,供体和受体碳的再杂化均落后于H隧穿。这与醇脱氢酶的观察结果完全相反,在醇脱氢酶中显示了酶运动在催化作用中的重要性。

    The reactions of 10a-peroxyflavins have been examined to increase understanding of the oxidative and chemiluminescent reactions catalysed by the flavin co-enzymes. A remarkable series of structural requirements in the peroxides used has been uncovered, and in addition to serving as models for the mechanism of bacterial luciferase, they constitute a set of new chemiluminescent reactions.

    Tropylium, xanthylium, and tritylium salts characterized by different stabilities differently reacted with biologically active amines. The reactions of tropylium perchlorate and tetrafluoroborate with 4-(cyclohepta-2,4,6-trien-1-yl)aniline was accompanied by hydrolysis of the N-(cyclohepta-2,4,6-trien-1-yl) derivative, the N-xanthenyl derivative underwent dehydrogenation, whereas tritylium perchlorate
    以不同稳定性为特征的Tropylium,xanthylium和trtylium盐与生物活性胺的反应不同。高氯酸对钾盐和四氟硼酸盐与4-(环庚-2,4,6-三烯-1-基)苯胺的反应伴随着N-(环庚-2,4,6-三烯-1-基)衍生物的水解,N-黄嘌呤衍生物进行了脱氢,而高氯酸叔丁基鎓不能与4-(环庚-2,4,6-三烯-1-基)苯胺反应。嘧啶-2-胺与对苯二甲基鎓,x鎓和三苯铵盐的反应以高收率提供了氨基中一个氢原子的取代产物。所述Ñ取代嘧啶-2-胺衍生物是稳定的,并没有观察到它们的脱氢也不水解。
