observed, which is different than the normal H/D kinetic isotope effects (KIEs) usually observed for polar aromatics. This result indicated that the oxidation started by photo-induced hvb+ can be the rate-determiningstep.
在TiO 2水溶液中弱极性芳族化合物的光催化羟基化反应中,观察到一系列的反向H / D KIE为0.7-0.8,这与通常在极性芳族化合物中观察到的正常H / D动力学同位素效应(KIEs)不同。该结果表明,由光诱导的h vb +开始的氧化可以是速率确定步骤。

Abstract 2H-1,4-Benzoxazin-3(4H)-one has been identified as an intermediate in the biosynthesis of cyclic hydoxamic acids in maize by showing that the deuterium labelled compound is incorporated into DIMBOA with high retention of deuterium and high efficiency, by trapping radioactivity from [ 14 C] anthranilic acid in a pool of unlabelled benzoxazinone administered to maize shoots, and by showing that
