Abstract

Spectra and basicity measurements indicate that in aqueous solution 9-hydroxyacridine 10-oxide exists in equilibrium with an approximately equal amount of 10-hydroxyacridone. 9-Mercaptoacridine 10-oxide exists in aqueous solution as such, in equilibrium with a comparable amount of 10-hydroxythioacridone.
