The 1,4-palladium shift strategy allows the functionalization of remote C-H bonds that are difficult to reach directly. Reported here is a domino reaction proceeding by C(sp3 )-H activation, 1,4-palladium shift, and amino- or alkoxycarbonylation, which generates a variety of amides

The synthesis of various substituted fluoren-9-ones has been accomplished by a novel palladium-catalyzed cyclocarbonylation of o-halobiaryls. The cyclocarbonylation of 4'-substituted-2-iodobiphenyls produces very high yields of 2-substituted fluoren-9-ones bearing either electron-donating or electron-withdrawing substituents. 3'-Substituted 2-iodobiphenyls afford in excellent yields with

The intramolecular coupling of two C(sp3 )-H bonds to forge a C(sp3 )-C(sp3 ) bond is enabled by 1,4-Pd shift from a trisubstituted aryl bromide. Contrary to most C(sp3 )-C(sp3 ) cross-dehydrogenative couplings, this reaction operates under redox-neutral conditions, with
