of phase-transfer halogenations (Br and I) of alkanes, significant H/D kineticisotopeeffects (KIE = 4-5) indicate that hydrogen abstraction is rate limiting. The excellent agreement of computed and experimentally determined H/D KIE as well as trapping experiments support the involvement of trihalomethyl radicals in the activation step.
在烷烃的相转移卤化(Br和I)范围内,显着的H / D动力学同位素效应(KIE = 4-5)表明氢的提取是速率限制。计算和实验确定的H / D KIE以及捕获实验的极好的一致性支持了三卤甲基自由基参与活化步骤。
