π-3H5 Fe (CO)3X (X=Cl, Br, and I) was decomposed with molecular oxygen in several solvents. It was found that the iron atom of the complex was oxidized, and oxygen molecule consequently was reduced and activated in every case regardless of the kind of solvents. The process for the coordination of oxygen molecule to the complex, however, depended much on the nature of solvents : in solvents such as alcohols or acetone, the direct substitution of oxygen molecule with the halogen atom of the complex took place, while in solvents such as dimethyl sulfoxide, the complex was decomposed by the solvent to form π-C3H5 Fe (CO)3, to which oxygen molecule was then coordinated. The resulting activated oxygen oxygenated the allyl ligand or abstracted the hydrogen atom from the substrate.
