Clear cut: For the title reaction, O2, the ideal oxidant, was used as the only oxidizing reagent. The dimer intermediate (see scheme) and isotopic labeling control experiments with 18O2 partially disclosed the reaction mechanism.
清晰:对于标题反应,使用理想的氧化剂O 2作为唯一的氧化剂。用18 O 2进行的二聚体中间体(参见方案)和同位素标记对照实验部分揭示了反应机理。
