原始语种摘要: Abstract(#br)The electrochemical oxidation of catechols ( 1a – c ) has been studied in the presence of 6-methyl-1,2,4-triazine-3-thion-5-one 3 in aqueous sodium acetate, using cyclic voltammetry and controlled-potential coulometry. A plausible mechanism for the oxidation of catechols and their reaction with 3 is presented. All the catechol derivatives ( 1a – c ) were converted into 7 H -thiazolo[3,2- b ]-1,2,4-triazin-7-one derivatives ( 6a – c ) through a Michael-type addition reaction of 3 to anodically generated o -quinones. The electrochemical syntheses of 6a – c were successfully performed in one pot in an undivided cell using an environmentally friendly method with high atomic economy.
