The kinetics of the iodine-catalyzed bromination of phenanthrene have been determined as identical with those of benzene. This is offered as proof of the identity of mechanism for the bromination of aromatic compounds in general with that previously proposed for phenanthrene. This mechanism involves addition of a positive bromine ion to the unsaturation of the aromatic nucleus followed by catalytic elimination of a hydrogen ion to yield the substitution product. It has been found that the equilibrium for the bromine-iodine reaction in carbon tetrachloride solution agrees with the determinations of Bodenstein and Schmidt for the gas phase reaction at considerably higher temperatures. © 1938, American Chemical Society.
