The present disclosure relates to iron-containing compounds including a 2,6-diimino(heteroaryl) ligand useful for producing substituted-cyclo-alkanes, such as vinyl cyclobutanes. The present disclosure provides new and improved iron-containing catalysts with enhanced solubility in hydrophobic (nonpolar) solvents.

Provided is a separation membrane that is suitable for use in separating one or more hydrocarbons from a hydrocarbon mixture. More specifically, the separation membrane includes a porous support for which acid content is not substantially detected by ammonia temperature programmed desorption in a temperature range of higher than 450° C. and not higher than 600° C. and a porous separation layer containing a zeolite that is disposed on the porous support.

A method for making an alkyl cyclobutane fuel, which includes obtaining a solution of at least one alpha olefin. A catalyst is added to the solution, thereby generating a mixture of dimers. The mixture is hydrogenated, thereby converting the dimers to hydrogenated dimers. The mixture is purified to produce an alkyl cyclobutane fuel.
