Abstract

Abstract Some electrophilic substitution reactions on 1, 3-benzoxathiole derivatives are described. Bromination and acylation reactions take place in position 5, ie, para to the oxygen atom. 1, 3-Benzoxathiole nitration yields a mixture of the corresponding sulfoxide and of the 6-nitro derivative when performed with 33% nitric acid, while, using a mixture of 40% nitric acid and acetic acid or acetyl nitrate, the 6-nitroderivative is obtained together ...
