Tug of war : Comprehensive DFT computational exploration of the reaction mechanisms predicts that the barriers for Br 2 addition processes to benzene, naphthalene, anthracene, and phenanthrene in isolation (i.e., in the absence of catalysts, see picture) and in simulated CCl 4 solution can be even lower than the barriers for direct substitution. Moreover, substitution products also can arise from stepwise Br 2 addition–HBr elimination routes.
