  [15N, 15N′]4, [18O]4, and [2-14C]4 were carried out. Kinetic isotope effects (KIE) were calculated from measurements of isotopic ratios in both recovered 4 and the product, 2-hydroxyazobenzene (6). Analogous rearrangement of mixtures of 2,2′-azoxynaphthalene (8) with [15N, 15N′]8 and [1,1′-13C2]8 were carried out and KIE were calculated from isotope ratios in the product. The results (particularly the

  进行了偶氮苯 4 和依次 [15N, 15N']4、[18O]4 和 [2-14C]4 的混合物的光重排。动力学同位素效应 (KIE) 是根据回收的 4 和产物 2-羟基偶氮苯 (6) 中同位素比率的测量值计算得出的。对 2,2'-偶氮萘 (8) 与 [15N, 15N']8 和 [1,1'-13C2]8 的混合物进行了类似的重排，并根据产物中的同位素比计算了 KIE。结果（特别是缺乏氮 KIE）共同表明，如果类恶二唑中间体参与这些重排，则其形成而不是分解中存在活化屏障。

  Of a selection of aromatic monoamines examined only β-naphthylamine was oxidized by potassium superoxide and formed dibenzo[a,h]phenazine, dibenzo[a,i]phenazine and 1-hydroxy-2,2′-azonaphthalene, the latter product indicating that the hydroxyl radical may be involved in superoxide oxidations.

  在检查的一系列芳香族单胺中，只有β-萘胺被过氧化钾氧化并形成了二苯并[a，h]吩嗪，二苯并[a，i]吩嗪和1-羟基-2,2'-氮杂萘，后者表明羟基可参与超氧化物的氧化。
