σ‐Bonded organic groups in transition‐metal complexes can rearrange to π‐bonding ligands and vice versa: the classic example is the formation of π‐arenechromium complexes from σ‐arylchromium compounds. Rearrangements of this kind can be induced, inter alia, by reactions of the metal or of the ligand, as well as by migration or insertion of a ligand. Rearrangements play a role in many industrial processes, including the polymerization and isomerization of olefins and the hydroformylation of olefins.
