Abstract: As tests of quantum mechanical theories that predict the spin of the ground state of non-Kekulb molecules, precursors to two such species were synthesized: the" C2/series, initiated by photolysis of lH, laH, 2H, 4H, 4aH, SH, SaH, 6bH-l, S-di-methylenedicycloprop [a, h]-s-indacene-2, 4-dione (13) to a primary triplet photolysis product, which upon selective further irradiation is converted to 3, 6-dimethyleneanthracenediyl-l, 8-dioxy (7), and the" ...
