The stereochemistry of the TOCO reaction is found to be temperature dependent: increasing amounts of cis addition products (approaching 50%) are formed as the temperature is lowered to −23° and also when the temperature is raised to ca 60°. The sensitivity of this temperature effect depends on the electronic character of the substituent present in the benzenethiol. The product distribution under a
发现TOCO反应的立体化学是温度依赖性的:随着温度降低至-23°,并且当温度升高至约60°时,形成的顺式加成产物的量增加(接近50%)。该温度效应的敏感性取决于苯硫醇中存在的取代基的电子特性。检查了各种实验条件下的产物分布和TOCO反应的动力学,从而得出了一个自洽的机理。
