1, 3-Dipolar Cycloadditions to Polycyclic Aromatic Hydrocarbons

The results of a 1, 3-dipolar cycloaddition reaction involving polyaromatic hydrocarbons (PAHs) as the dipolarophiles and the 1, 3-dipole formed by the ring-opening of a 5-oxabicyclo[2.1.0]pentane are reported. PAHs such as naphthalene, anthracene, benzanthracene, acenaphthene, phenanthrene, 9, 10-phenanthroline, gave mixtures of endo- (major) and exo- adducts, while fluorenone and anthraquinone yielded adducts across the carbonyl double bond. Only rare examples of cycloaddition reactions where anthracene acts as a dipolarophile are reported in literature
