The isoprenedimers generated are a mixture of [2 + 2], [4 + 2] and [4 + 4] cycloadducts, and after hydrogenation this mixture is nearly ideal as a drop-in jet fuel. Importantly the photodimerization can be carried out at ambient conditions. However, the high content of hydrogenated [2 + 2] dimers in our isoprenedimer mix lowers the flash point below the threshold (38 °C); yet, these dimers can be

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.
