  Halogen-Bond-Induced Consecutive C_sp³–H Aminations via Hydrogen Atom Transfer Relay Strategy

  摘要：

  The utilization of a halogen bond in a number of chemical fields is well-known. Surprisingly, the incorporation of this useful noncovalent interaction in chemical reaction engineering is rare. We disclose here an uncommon use of halogen bonding to induce intermolecular C-sp(3)-H amination while enabling a hydrogen atom transfer relay strategy to access privileged pyrrolidine structures directly from alkanes. Mechanistic studies support the presence of multiple halogen bond interactions at distinct reaction stages.

• Aluminum Triflate as a Powerful Catalyst for Direct Amination of Alcohols, Including Electron‐Withdrawing Group‐Substituted Benzhydrols

  Direct aminations of allylic alcohols, benzylic alcohols, and benzhydrols with electron‐withdrawing (F, Br, I, NO2, or CN) substituents were efficiently catalyzed by aluminum triflate [Al(OTf)3] to afford the corresponding biarylamines in high yield, and the dibromo‐substituted product was further transformed into letrozole.

  三氟甲磺酸铝[Al（OTf）3 ]有效催化具有吸电子（F，Br，I，NO 2或CN）取代基的烯丙醇，苄醇和苯羟基的直接胺化，从而以高收率提供相应的联芳基胺，然后将二溴取代的产物进一步转化为来曲唑。

  Represented herein is a simple thiol identified as an effective precursor to photochemically form a carbocation. Thanks to the thiyl radical rapid transformation to disulfide, which serves not only to stabilize the generated thiyl radical but also to allow the second electron transfer to form a carbocation. The resulting carbocations, including primary benzylic, secondary, and tertiary carbocations

  本文代表的是一种简单的硫醇，被鉴定为光化学形成碳正离子的有效前体。由于硫基自由基快速转化为二硫化物，这不仅可以稳定生成的硫基自由基，还可以允许第二次电子转移形成碳正离子。所得的碳正离子，包括伯苄基碳正离子、仲碳正离子和叔碳正离子，可以与氮、氧和碳亲核偶联伴侣以及复杂的药物分子顺利偶联，同时在空气中形成元素硫。
