NUCLEOPHILIC AROMATIC SUBSTITUTION: FADING OF BENZOTHIAZOLIUM AZO DYES IN ALKALINE SOLUTION

Benzothiazolium azo dyes bearing a 4'-amino function hydrolyse in alkali according to the equation:.The reaction is catalysed by amines; a dye with R1=CH2CH2OH exhibits a third-order kinetic term (k3->) which is not observed with dyes without a hydroxyl group in R1 or R2.Methoxide ion gives reversible formation of a ?-bonded adduct with the dyes; benzothiazolium azo dyes with weakly basic amine substituents react with hydroxide ion to form adducts which regenerate the azo dye on addition of acid.
