Palladium-catalyzed [2 + 2 + 2] cycloadditions of 3,4-didehydrophenanthrene and 1,2-didehydrotriphenylene.
Palladium-catalyzed [2 + 2 + 2] cycloaddition reactions of 3,4-didehydrophenanthrene (3,4-phenanthryne) and 1,2-didehydrotriphenylene (1,2-triphenylyne) afford sterically congested polycyclic aromatic hydrocarbons with novel structures.
