In the presence of molecular sieves under base free conditions organic halides are successfully carbonylated under carbon monoxide pressure with water or alcohols catalyzed by Co or Pd complex to generate the corresponding carboxylic acids or esters, respectively, in good yields.
Visible-Light Enabled C(s<i>p</i><sup>3</sup>)–C(s<i>p</i><sup>2</sup>) Cross-Electrophile Coupling via Synergistic Halogen-Atom Transfer (XAT) and Nickel Catalysis
We herein report the first visible-light-mediated cross-coupling of unactivated alkyl iodides with aryl bromides through synergistic halogen atom transfer (XAT) and nickel catalysis. This simple protocol operates undermild reaction conditions and tolerates a variety of functional groups affording C(sp3)–C(sp2) cross-coupling products in good to moderate yields.
我们在此报告了第一个可见光介导的未活化烷基碘与芳基溴通过协同卤素原子转移 (XAT) 和镍催化的交叉偶联。这个简单的协议在温和的反应条件下运行,并容忍各种官能团,以良好至中等的产率提供 C(s p 3 )–C(s p 2 ) 交叉偶联产物。
