We report a palladium-catalyzed carbon carbon bond-forming reaction between aryl iodides and alkenes. In contrast to traditional cross-coupling reactions, two new bonds are formed, and all of the atoms in the starting materials are incorporated into the product. The use of a palladium catalyst with bulky phosphine ligands is found to be crucial for reactivity.

light-catalyzed carbohalogenation reaction is reported. A nickel catalyst and an inexpensive phosphine ligand promote the reaction of aryl iodides and aryl bromides with π systems to enable the construction of a library of halogenated heterocyclic scaffolds. Mechanistic studies provide insight regarding fundamental steps of the catalytic cycle, including the reversible C–X bond formation via deuterium labeling
