Nickel-Catalyzed Reaction of Benzamides with Bicylic Alkenes: Cleavage of C–H and C–N Bonds

The nickel-catalyzed reaction of aromatic amides that contain an 8-aminoquinoline as a directing group with bicyclic alkenes, such as norbornene and 1,4-dihydro-1,4-epoxynaphthalene, results in the cleavage of both the C-H bond at the ortho-position of the benzene ring and the C(O)-N bond to give methanofluoren-9-one and 1,4-epoxyfluoren-9-one derivatives. Both Ni(OTf)2 and Ni(cod)2 show a high catalytic activity. The presence of AgOAc is...
