The ozonolysis of indigo was investigated. Indigo[ 1 ] was ozo nated to isatin [ 2 ], from which isatoic anhydride [ 3 ] and a trace amount of “o-benzoylenequinazolone”(indolo[2, 1-b]quinozoline-6, 12-dione) [ 4 ]were produced. When indigo was ozonated in water, isatin and hydrogen peroxide[ 5 ] were produced. The reaction could be explained by the norm al ozonolysis mechanism of C=C double bond of indigo.
