Abstract
It was established that N-acetylindoxyl oxime is converted to N-acetylindoxyl acetyloxime when it is heated to 50 ° C in a mixture of acetic acid and acetic anhydride. If the reaction is carried out by refluxing, N-acetyl-2-acetoxy- 3-acetam-idoindole, which undergoes rearrangement to 1,3-diacetyl-3-acetamidooxindole when it is heated, is also formed.
