Infobox references

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. It is the parent compound for the phosphorous-containing phosphaphenalenes.

Phenalene is deprotonated by potassium methoxide to give the phenalenyl anion.
