Aromatic Ring Bromination in 1,4-Benzothiazines, 1,4-Benzoxathianes and 1,4-Benzodithianes: the Occurrence of Vicarious Nucleophilic Substitution of Hydrogen and Electrophilic Aromatic Substitution Mechanisms
1,4-benzodithianes, 1,4-benzothiazines and 1,4-benzoxathianes, when treated with bromine in anhydrous chloroform, undergo regiospecific monobromination at the aromatic ring.Based on semiempirical quantum mechanical calculations, the regiochemistry of the reaction in the case of 1,4-benzothiazines and 1,4-benzoxathianes was shown to be consistent with a charge-controlled electrophilic aromatic substitution reaction where the Br+ species comes from monobromosulfonium ions (as 2).On the contrary, in the case of 1,4-benzodithianes, the bromination is accomplished by Br- via an orbital-controlled vicarious nucleophilic substitution of hydrogen occurring on dibromodisulfonium ions (as 4).
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Electric Literature of 3080-99-7. In my other articles, you can also check out more blogs about 3080-99-7
