Herein we have developed a Ni-catalyzed protocol for the synthesis of linear ketones. Aryl, alkyl, and heteroaryl ketones as well as alcohols yielded the monoselective ketones in up to 90% yield. The catalytic protocol was successfully applied in to a gram-scale synthesis. For a practical utility, applications of a steroid derivative, oleyl alcohol, and naproxen alcohol were employed. Preliminary catalytic
本文中,我们已经开发了镍催化的线性酮合成方案。芳基,烷基和杂芳基酮以及醇类以高达90%的产率生成单选择性酮。催化方案已成功应用于克级合成。为了实用,使用了类固醇衍生物,油醇和萘普生醇的应用。进行了初步催化研究,包括分离镍中间体和确定的Ni–H物种,以及一系列氘标记实验。
