The decomposition of 10-substituted anthralin derivatives in dimethyl sulfoxide and ethanol was determined. While 10-omega-phenylalkylidene derivatives were thoroughly stable, 10-omega-phenylacyl-substituted compounds were slowly degraded to danthron and the corresponding carboxylic acids. However, the stability of these derivatives was markedly improved as compared to that of anthralin. Determination of the pK(a) values showed that the omega-phenylacyl derivatives were somewhat stronger acids than anthralin, while omega-phenylalkylidene-substitution generally leaves the acidity of the anthralin part unchanged.
