title: [Contribution to the erythroquine and thalleioquine reaction].
abstract: The 8,8'-biquinoline-5,5'-diones 2A are formed by the erythroquine and thalleioquine reaction from the 6-methoxyquinolines 1 as model compounds. The red substances 2A react with hydrochloric acid to yield the yellow biquinolinedihydrochlorides 3. The structure of 3b dihydrate is determined by X-ray crystal analysis. The redox properties of 2A are investigated by voltammetric methods.
