Improved Preparation of 6,13-Dichlorotriaryldioxazines using (Diacetoxyiodo)benzene
Abstract
6,13-Dichlorotriaryldioxazines (DClTADO) 1 have been synthesized from 2,5-bis(arylamino)-3,6-dichloro-1,4-benzoquinones (BADClBQ) 2 by oxidation with (diacetoxyiodo)benzene (DIB) under mild conditions in good yields.
