A process for the oxidation of alkanes or alkenes is described. The process uses a hydrocarbyl hydroperoxide as an oxidizing agent in combination with a ruthenium catalyst and optionally a hydrogen bromide or hydrobromide acid promoter. The products of the oxidation are alcohols, ketones or a mixture of both.

Process for the oxidation of hydrocarbons

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.
