We report a method that ensures the selective alkylation of benzamides and aromatic ketones at the para-position via cooperative nickel/aluminum catalysis. Using a bulky catalyst/cocatalyst system allows reactions between benzamides and alkenes to afford the corresponding para-alkylated products. The origin of the high para-selectivity has also been investigated by density functional theory calculations
我们报告了一种通过镍/铝协同催化确保苯甲酰胺和芳族酮在对位选择性烷基化的方法。使用庞大的催化剂/助催化剂体系允许苯甲酰胺和烯烃之间的反应得到相应的对位烷基化产物。还通过密度泛函理论计算研究了高对位选择性的起源。
