Organometallic catalysts have enabled simple preparation routes for obtaining a great variety of organic compounds. The rupture of carbon-halogen (C-X) bonds is frequently a key step in the catalytic formation of C-C bonds. Most catalytic cycles consist in a series of elemental steps where several electrons (typically, two) are exchanged between a metallic center and its ligands, with oxidative additions (OA) and reductive eliminations being the most representative processes of this kind.Here, we report an oxidative addition of 2-fluoroiodobenzene to a Rh(I) complex which yields an unusual Rh(II) product instead of the expected Rh (III) complex.
