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, 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
74 words
A process for the conversion of C 2 to C 10 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 heterocylic 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
74 words
A process for the conversion of C 2 to C 10 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 heterocylic 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
13 words
A process according to claim 1 wherein the hydrocarbyl hydroperoxide is t-butyl hydroperoxide.
Claim 4
Dependent Claim
16 words
A process according to claim 1 wherein the complex is a phthalocyanine or a porphyrin complex.
Claim 5
Dependent Claim
22 words
A process according to claim 1 wherein the complex has no axial ligands and is an iron (11) or manganese (11) complex.
Claim 6
Dependent Claim
23 words
A process according to claim 1 wherein the complex has no axial ligands and is an iron (111) or manganese (111) cationic complex.
Claim 7
Dependent Claim
17 words
A process according to claim 1 wherein the complex has a non-coordinating or weakly coordinating axial ligand.
Claim 8
Dependent Claim
36 words
A process according to claim 1 wherein the complex is formed `in-situ` from a complex having a strongly coordinating axial ligand by the addition of an acid selected from sulphuric acid, boric acid and benzoic acid.
