A gold-catalyzed intramolecular insertion reaction of strictly unactivated C(sp3)−H bonds is described. The reaction uses readily available starting materials and benefits from extremely simple reaction conditions. A library of structurally diverse scaffolds bearing a C(sp2)−Br bond has been obtained. In addition, an original reaction pathway in gold catalysis involving a concerted insertion on a gold-stabilized
