We developed a palladium-catalyzed C–H transformation that enabled the synthesis of ketones from aldehydes and (hetero)aryl halides. The use of picolinamide ligands was key to achieving the transformation. Heteroaryl ketones, as well as diaryl ketones, were synthesized in good to excellent yields, even in gram-scale, using this reaction. Results of density functional theory (DFT) calculations support the C–H bond activation pathway.

钯通过C–H键活化从醛和（杂）芳基卤化物催化合成二芳基酮

我们开发了钯催化的CH转化，可从醛和（杂）芳基卤化物合成酮。吡啶甲酰胺配体的使用是实现转化的关键。使用该反应，即使以克为单位，杂芳基酮以及二芳基酮也以良好至优异的产率合成。密度泛函理论（DFT）计算的结果支持C–H键激活途径。
