2-diarylation of alkenyl ketones with aryl iodides and arylboronic esters is reported. Ketones with a variety of substituents serve as effective directing groups, offering high levels of regiocontrol. A representative product is diversified into a wide range of useful products that are not readily accessible via existing 1,2-diarylation reactions. Preliminary mechanistic studies shed light on the binding
报道了镍催化的烯基酮与芳基碘化物和芳基硼酸酯的 1,2-二芳基化反应。具有多种取代基的酮可作为有效的导向基团,提供高水平的区域控制。代表性产品被多样化为各种有用的产品,这些产品不容易通过现有的 1,2-二芳基化反应获得。初步机理研究揭示了底物的结合模式,哈米特分析揭示了电子因素对初始速率的影响。
