The reactions of a series of α,α- and β,β-disubstituted naphthalenes containing two different substituents OR1 (R1 = H, SO2CH3) and OR2 (R2 = CH3, SO2CH3) with sulfurtrioxide in CD3NO2 has been studied. The electronic directing effect of the hydroxy group was found to be dominant over that of the methoxy group, which in turn dominates that of the mesyloxy group. Upon reaction with an excess of sulfur
