Photogeneration of Polymer-Anchored Catalytic Species from Iron Carbonyls

Recently a number of studies have shown that coordinatively unsaturated transition metal complexes, which are capable of serving as catalysts for a variety of reactions involving olefins, may be generated by photolysis.1–6 Coordinative unsaturation can be obtained by light-induced ligand dissociation or metal-metal bond dissociation. Light-generated catalysts may be genuinely unique since the catalyst is the result of an excited state decay process.
