    amides as stable and readily accessible acyl surrogates. N‐acylsuccinimides served as efficient acyl reagents for the streamlined synthesis of synthetically useful ketones from simple C(sp3)−H substrates. Detailed mechanistic investigations using both computational and experimental mechanistic studies were performed to construct a detailed and complete catalytic cycle. The origin of the superior reactivity
    在催化中,无所不在的热力学稳定的酰胺和脂族C(sp 3)-H键的各种功能化利用一直是挑战。特别地,尚未实现两个官能团之间的直接偶联。在这里,我们报告了两个具有挑战性的键,酰胺C-N和未活化的脂肪族C(sp 3)-H,通过金属光催化还原催化直接酰化脂肪族的CH-H键,利用酰胺作为稳定且易于接近的酰基替代物的协同活化。N-酰基琥珀酰亚胺可作为有效的酰基试剂,用于从简单C(sp 3)简化合成有用的酮的合成)-H基板。使用计算和实验机理研究进行了详细的机理研究,以构建详细而完整的催化循环。发现N-酰基琥珀酰亚胺比其他更具反应性的酰基源(如酰氯)具有更高反应活性的起源是一种罕见的反应途径,其始于在氧化添加酰基底物之前的CH活化。

    effecting a rapid Saegusa-type oxidation of enol acetates is reported. This new method relies on the in situ elimination of an α-bromo intermediate to generate α,β-unsaturated ketones using copper(II) bromide. The methodology developed was applied to a range of substrates including a cyclohexanone, which could be directly converted to the corresponding phenol derivative. A catalytic system in which a
