Exclusive Aromatic vs Aliphatic C-H Bond Functionalization by Carbene Insertion with Gold-based Catalysts

The direct functionalization of aromatic C-H bonds by carbene insertion from diazocompounds 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 a several NHC ligands i...

Sumario:The direct functionalization of aromatic C-H bonds by carbene insertion from diazocompounds 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 a several NHC ligands in Au(I) and Au(III) complexes has been performed. A potential application in profen derivatives has also been developed
