Abstract
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, eg 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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
69 words
A process for the conversion of alkanes into a mixture of their corresponding alcohol and ketone derivatives which process comprises reacting the alkane with a hydrocarbyl 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, which complex has either no axial ligand or an axial ligand which is non-coordinating or weakly coordinating.
Claim 2
Dependent Claim
69 words
A process for the conversion of alkanes into a mixture of their corresponding alcohol and ketone derivatives which process comprises reacting the alkane with a hydrocarbyl 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, which complex has either no axial ligand or an axial ligand which is non-coordinating or weakly coordinating.
Claim 3
Dependent Claim
19 words
