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-determining step.
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。
