The direct functionalization of aromatic C–H bonds by carbene insertion from diazo compounds catalyzed by gold complexes with N-heterocyclic ligands is described. The reaction is completely selective toward the Csp2–H bonds, other Csp3–H bonds remaining unreacted. A study with several NHC ligands in Au(I) and Au(III) complexes has been performed. The potential application of this strategy to give profen
描述了通过金与N-杂环配体的配合物催化的重氮化合物通过卡宾插入而使芳族CH键直接官能化的方法。该反应对C sp 2完全选择性-H键,其他C sp 3 -H键保持未反应。已经对Au(I)和Au(III)配合物中的几种NHC配体进行了研究。还已经研究了该策略用于产生profen衍生物的潜在应用。
