1H-Phenalene, often called simply phenalene is a polycyclic aromatic hydrocarbon (PAH). Like many PAHs, it is an atmospheric pollutant formed during the combustion of fossil fuels.^[2] It is the parent compound for the phosphorus-containing phosphaphenalenes.

The name was proposed by German chemists in 1922 as a contraction of periphenonaphthalene.^[3]

Reactions

Phenalene is deprotonated by potassium methoxide to give the phenalenyl anion.^[4]
