We have developed a nickel-catalyzed hydroarylation of alkenes using aryl halides as coupling partners. Excellent anti-Markovnikov selectivity is achieved with aryl-substituted alkenes and enol ethers. We also show that hydroarylation occurs with alkyl substituted alkenes to yield linear products. Preliminary examination of the reaction mechanism suggests irreversible hydrometallation as the selectivity determining step of the hydroarylation.

我们开发了一种镍催化的烯烃加氢芳基化方法，使用芳基卤化物作为偶联伙伴。使用芳基取代的烯烃和烯醇醚可实现出色的抗马可夫尼科夫选择性。我们还表明，烷基取代的烯烃发生加氢芳基化，产生线性产物。反应机理的初步研究表明不可逆的加氢金属化是加氢芳基化的选择性决定步骤。 |
