Photolysis of anthracene in a mixture consisting of 2% CF3SO3H in CF3CO2H (w/w), where anthracene is partially protonated, gives a mixture of oxidized, neutral and reduced monomeric and dimeric products, initiation of this chemistry being photoinduced electron transfer from anthracene to protonated anthracene.

The predominant initial products in the thermal chemistry of anthracene are 2,9'-bianthracenyl and 9,10-dihydroanthracene.Over the range 350-500 deg C, in the gas and liquid phase, this reaction follows second-order kinetics with k/M-1 s-1 = 107.37+/-0.27 exp.The only other major products is 1,9'-bianthracenyl, which at low extents of reaction is formed at a rate one-seventh that of 2,9'-bianthracenyl.Anthracene selectively forms biaryls with the following compounds (relative rate constants for forming the major cross-biaryls are in parentheses): naphthalene (0.5) phenanthrene (0.2), biphenyl(0.2), diphenyl ether (0.2).A kinetic analysis of results leads us to propose that the initial step in these reactions is the reversible formation of a diradical via coupling of two ground-state molecules.This is followed by a rate-limiting, intramolecular H-transfer step resulting in a dihydrobiaryl molecule, which then rapidly loses two hydrogen atoms, probably by free radical reactions, to form the major biaryl products.Minor biaryl products are formed in a less selective manner in a reaction catalyzed by 9,10-dihydroanthracene.Aryl radicals are likely intermediates in these reactions.
