The extreme readiness of replacement of fluorine by hydrogen in catalytic hydrogenations of fluoro- and difluorobutenedioic acids and their esters is believed to be caused by participation of double bonds in the hydrogenation processes. The mechanism of the hydrogenolysis suggested in the previous paper has been tested using deuterium and its mixtures with hydrogen for the reductions. Based on the results
据信在
氟代和二
氟丁烯二酸及其酯的催化氢化中用氢替代
氟非常容易,这是由于双键参与氢化过程引起的。先前论文中提出的氢解机理已通过使用
氘及其与氢的混合物进行还原的方法进行了测试。根据结果,对双键的参与方式进行了修改,以符合实验证据。给出并解释了
