✦ Synopsis

Photochemical and Thermal Rearrangements of 2-Arylamino-1-(4tert-butylphenoxy)-9,10-anthraquinones.

-Irradiation of the title 2-arylaminoanthraquinones (III) proceeds by migration of the tert-butylphenyl group to the 9-carbonyl oxygen to furnish 1,10-anthraquinones [as hydrolysis products (IV)] or by Smiles rearrangement to give diarylamino derivatives (V). Smiles rearrangement is also observed under basic (KOH-DMSO) or thermolysis conditions. -(MAINAGASHEV, I.
