Abstract
A method for making a fuel includes reacting a conjugated diene or a mixture of conjugated dienes with a catalyst selected from the group consisting of a low valent iron catalyst stabilized with a pyridineimine ligand, an iron precatalyst coordinated to the pyridineimine ligand that is activated with a reducing agent, a low oxidation state Fe complex stabilized with a pyridineimine ligand and a coordinating ligand, and combinations thereof, thereby forming a substituted cyclooctadiene. The substituted cyclooctadiene is then hydrogenated, thereby forming cyclooctane fuel.

A method for making a cyclooctane fuel, comprising:
- reacting a conjugated diene or a mixture of conjugated dienes with a catalyst selected from the group consisting of a low valent iron catalyst stabilized with a pyridineimine ligand, an iron precatalyst coordinated to the pyridineimine ligand that is activated with a reducing agent, a low oxidation state Fe complex stabilized with a pyridineimine ligand and a coordinating ligand, and combinations thereof, thereby forming a cyclooctadiene with a structure of:
- wherein each R is independently a hydrogen atom or an alkyl group;
- hydrogenating the cyclooctadiene, thereby making the cyclooctane fuel with the structure of:
- wherein each R is independently a hydrogen atom or an alkyl group.
