• Oxyarylation and Aminoarylation of Styrenes Using Photoredox Catalysis
  作者：Gabriele Fumagalli、Scott Boyd、Michael F. Greaney

  DOI：10.1021/ol401940c

  日期：2013.9.6

  A three-component coupling of styrenes is reported, using photoredox catalysis to achieve simultaneous arylation and C–O or C–N bond formation across the styrene double bond.

  据报道，通过光氧化还原催化，苯乙烯可以实现三组分偶联，同时实现芳基化和跨苯乙烯双键的C–O或C–N键的形成。
• Gold-Catalysed Oxyarylation of Styrenes and Mono- and<i>gem</i>-Disubstituted Olefins Facilitated by an Iodine(III) Oxidant

  1‐Hydroxy‐1,2‐benziodoxol‐3(1H)‐one (IBA) is an efficient terminal oxidant for gold‐catalysed, three‐component oxyarylation reactions. The use of this iodine(III) reagent expands the scope of oxyarylation to include styrenes and gem‐disubstituted olefins, substrates that are incompatible with the previously reported Selectfluor‐based methodology. Diverse arylsilane coupling partners can be employed

  1-羟基1,2-苯并恶唑3（1 H）-一（IBA）是一种用于金催化的三组分氧化酰化反应的有效末端氧化剂。使用这种碘（III）试剂膨胀oxyarylation的范围，以包括苯乙烯和宝石二取代的烯烃中，与先前报道的基于的Selectfluor-方法不相容的基底。可以使用不同的芳基硅烷偶联剂，并且在苯并三氟化物中，均偶联显着减少。此外，IBA衍生的副产品可以回收和循环再利用。

  also radical precursors. Classic transition-metal-catalyzed and photochemical decarboxylation have shown their excellent site selectivity in radical chemistry. However, electrochemical decarboxylation with a long history hasn't got enough attention in recent years. In this work, the electrochemical oxidative decarboxylation and 1,2-aryl migration of 3,3-diarylpropionic acids have been introduced to construct

  羧酸化合物是重要的化学物质，广泛存在于各种天然产物中。它们不仅是亲核试剂，还是自由基的前体。经典的过渡金属催化和光化学脱羧在自由基化学中显示出出色的位点选择性。但是，近年来，电化学脱羧历史悠久，尚未引起足够的重视。在这项工作中，已引入3,3-二芳基丙酸的电化学氧化脱羧和1,2-芳基迁移，以与醇构建C–O键。值得注意的是，这种转变无需金属催化剂和外部氧化剂即可顺利进行。
• Transition-Metal-Free Catalytic Carboalkoxylation of Styrenes at Room Temperature

  Herein, we describe the first transition-metal-free catalytic carboalkoxylation of styrenes with aryl diazonium salts by Meerwein addition in the presence of a phenalenyl ligand at room temperature without requiring any light stimulation. This three-component reaction allows facile difunctionalization of styrene derivatives with various alcohols (such as 1, 2, and 3 degrees) as the source of alkoxy group during this transformation. The key intermediates and the transition states involved in this reaction path were unraveled by a series of control experiments coupled with density functional theory calculations. The full mechanistic investigation provides an understanding of the selectivity toward carboalkoxylation Meerwein arylation addition elimination) in the presence of various alcohols over the simple arylation to multiple bond (Meerwein arylation-elimination) reaction.
