  The direct carbonylative palladium catalyzed synthesis of monoprotected 1,3-ketoaldehydes is reported starting from aryl iodides applying near stoichiometric amounts of carbon monoxide. Besides representing platforms for a variety of heterocyclic structures, these motives serve as viable precursors for the highly relevant aryl methyl ketones.

  mechanism. The α-effect increases as the substituent X in the phenyl ring of 2a−f becomes a stronger electron-donating group. However, the magnitude of the α-effect for the reactions of 2a−f is small (e.g., kNhydrazine/kNglycylglycine = 4.6−13) regardless of the electronic nature of the substituent X. The small βnuc has been suggested to be responsible for the small α-effect. A solvent kinetic isotope

• Electro-oxidative C(sp3)–H Amination of Azoles via Intermolecular Oxidative C(sp3)–H/N–H Cross-Coupling
  作者：Jiwei Wu、Yi Zhou、Yuchen Zhou、Chien-Wei Chiang、Aiwen Lei

  DOI：10.1021/acscatal.7b03551

  日期：2017.12.1

  electrooxidative C(sp3)–H amination via intermolecular oxidative C(sp3)–H/N–H cross-coupling has been developed under metal- and oxidant-free conditions. The C(sp3)–H bonds adjacent to oxygen, nitrogen, and sulfur atoms could all react smoothly with various amines to give the corresponding products with moderate to good yields (30–93%). In addition, the C(sp3)–H bonds of benzylic and allylic are also tolerated

  已经开发了一种在无金属和无氧化剂条件下通过分子间氧化C（sp3）-H / N-H交叉偶联进行电氧化C（sp3）-H胺化的方法。与氧，氮和硫原子相邻的C（sp3）–H键均可以与各种胺顺利反应，从而以中等至良好的收率（30–93％）得到相应的产物。此外，该反应中还可以耐受苄基和烯丙基的C（sp3）–H键。初步的机理研究表明，四氢呋喃的C–H裂解可能不参与速率测定步骤。
