Cobalt-phosphine and cobalt-carbene catalysts have been developed for the hydroarylation of styrenes via chelation-assisted C-H bond activation, to afford branched and linear addition products, respectively, in a highly regioselective fashion. Deuterium-labeling experiments suggested a mechanism involving reversible C-H bond cleavage and olefin insertion steps and reductive elimination as the rate-
钴-膦和钴-卡宾催化剂已被开发用于通过螯合辅助 CH 键活化对苯乙烯进行加氢芳基化,以高度区域选择性的方式分别提供支化和线性加成产物。氘标记实验提出了一种机制,涉及可逆的 CH 键裂解和烯烃插入步骤,以及作为速率和区域选择性决定步骤的还原消除。
