  high reactivity of alkoxyl (RO·) radicals and their propensity to easily undergo β-scission or Hydrogen Atom Transfer (HAT) reactions, intermolecular alkoxylations involving RO· radicals are barely described. We report herein for the first time the efficient intermolecular trapping of alkoxyl radicals by silyl enol ethers. This photoredox-mediated protocol enables the introduction of both structurally

  由于烷氧基 (RO·) 自由基的高反应性及其容易发生 β 断裂或氢原子转移 (HAT) 反应的倾向，几乎没有描述涉及 RO· 自由基的分子间烷氧基化。我们在此首次报道了甲硅烷基烯醇醚对烷氧基自由基的有效分子间捕获。这种光氧化还原介导的协议能够将结构简单和更复杂的烷氧基引入范围广泛的酮和酰胺中。

  investigations show that the substrate undergoes rearrangement to an aldehyde under [1,2]-H-migration and cleavage of an oxygen-based leaving group. The leaving group is trapped as its formic ester, and the aldehyde is reduced and subsequently esterified to a formate. While the rearrangement to the aldehyde is catalyzed by sulfonic acids, the reduction step requires a unique catalyst system comprising

  在本文中，我们描述了酸/ Pd串联催化的乙二醇衍生物向末端甲酸酯的转化。机理研究表明，在[1,2] -H迁移和氧基离去基团的裂解下，底物发生重排成醛。离开的基团被捕获为其甲酸酯，醛被还原并随后酯化为甲酸酯。磺酸可催化醛的重排，而还原步骤则需要独特的催化剂体系，该体系包含Pd（II）-或Pd（0）-前体，其负载量低至0.75 mol％和a，a'-bis（二叔丁基膦基）-邻二甲苯作为配体。还原步骤利用甲酸作为易于处理的转移还原剂。

  between an iron(II)–benzilate complex and O2, oxidatively cleaves the aliphatic C−C bonds of α‐hydroxy ketones. In the cleavage reaction, α‐hydroxy ketones without any α‐C−H bond afford a 1:1 mixture of carboxylic acid and ketone. Isotope labeling studies established that one of the oxygen atoms from dioxygen is incorporated into the carboxylic acid product. Furthermore, the iron(II) complex cleaves
