- ELECTRONIC ABSORPTION SPECTRA AND STRUCTURE OF ISOMERIC DI(p-TOLYLAMINO)ANTHRAQUINONES
-
By analysis of the electronic absorption spectra and the data from quantum-chemical calculations it was shown that 1,4- and 9,10-di(p-tolylamino)anthraquinones exist in the 9,10- and 1,4-anthraquinonoid forms respectively.Tautomerism between the 1,10-anthraquinonoid and 9,10-anthraquinone imine structures was detected and proved for 4,9-di(p-tolylamino)-1,10-anthraquinone.
