Abstract
The chemical properties of pentalene and its isomers, as well as their cations, are considered. Pentalene is a chemically active compound that plays an important role in the formation and destruction of polyaromatic hydrocarbons (PAHs), which are the main components of soot microparticles. They arise during the combustion of fossil fuels and are considered as the most dangerous for human health anthropogenic aerosol atmospheric pollutants. The phenomenon of shift of aromatic/anti-aromatic properties of pentalene and its derivatives upon ionization (changes in the number of p-electrons) is also discussed.
