Figure 1.

Quantitative structure–activity relationship of the measured second-order rate constants for the reactions of all selected model compounds (except p-benzoquinone) with Br^• and the computed free energies of activation for electron transfer reactions (see Table 1). The aromatic compounds with reported k_Br• in the literature^10,12 are labeled as “(ref)” and are also shown for comparison. The literature values were not included in the regression.
