Transition metal-catalyzed remote hydrofunctionalization of alkenes is an efficient method to realize C(sp3)–H functionalization. However, remote hydrofunctionalization of alkenes with unactivated amines and alcohols has not been successfully developed to date. Herein, we report an efficient nickel-catalyzed remote hydroamination and hydroetherification of alkenes with unactivated amines and alcohols, accessing
过渡金属催化的烯烃远程加氢官能化是实现C(sp 3 )–H官能化的有效方法。然而,迄今为止尚未成功开发烯烃与未活化的胺和醇的远程加氢官能化。在此,我们报道了一种有效的镍催化的烯烃与未活化的胺和醇的远程加氢胺化和加氢醚化反应,获得了一系列具有良好至高产率(高达93%)和独特区域选择性的宝石-二胺和N , O-缩醛衍生物。机理研究和 DFT 计算表明,使用 2-iodo-2-methylpropane ( tBuI) 作为温和的氢化物源和自由基前体对于提供远程功能化产品至关重要。该研究工作提供了一种在远离烯烃双键的C(sp 3 )-H位置安装氨基或烷氧基的有效方法。
