title: Electrochemical method for the synthesis of disulfides of 2-(benzo[d]thiazol(or oxazol)-2-ylamino)-5-morpholinobenzenethiol.
abstract: Electrochemical synthesis of two new disulfides of 2-(benzo[d]thiazol(or oxazol)-2-ylamino)-5-morpholinobenzene thiols was carried out via the electrooxidation of 4-morpholinoaniline in the presence of 2-mercaptobenzothiazole and 2-mercaptobenzoxazole. Our results indicate that electrogenerated p-quinonediimine participated in a Michael-type addition reaction with 2-SH-benzazoles and after intramolecular nucleophilic substitution reaction and electrooxidative disulfide bond formation were converted to the corresponding disulfide compounds.
