  • Process for the conversion of an alkane to a mixture of an alcohol and a ketone
    Patent number: 4459427
    Abstract: A mixture of the alcohol and ketone derivatives of alkanes is produced by reacting the alkane with a hydrocarbyl hydroperoxide, eg t-butyl hydroperoxide, at ambient or elevated temperature and pressure in the presence as catalyst of an iron or manganese square planar complex having heterocyclic nitrogen-donor ligands, e.g. a porphyrin or phthalocyanine complex, which complex has either no axial ligands, eg the lower valency or cationic complex, or an axial ligand which is non-coordinating or weakly-coordinating.
