Abstract

Abstract: Two different products were obtained while 4-bromo-5-methylisatin was oxidized by separately using organic peroxy acids and Caros acid as the oxidizing agent. The chemical structures of the oxidation products were elucidated by spectra analysis to be a pair of isomer: novel compound 5-bromo-6-methyl-1H-benzo oxazine-2,3-dione and the known compound 5-bromo-6-methyl-1-Hbenzo oxazine-2,4-dione. The product is free of isomer for each reaction. The reaction mechanisms were also discussed.

Key words: Bromo-5-methylisatin, Oxidation, BaeyerVilliger reaction
