The nitration of 2,3'-biquinolyls in concentrated sulfuric acid with an equivalent amount of nitric acid at room temperature takes place exclusively at the 2-quinolyl fragment with the formation of the 5- and 8-nitro derivatives or their mixtures. The nitration of the 1',4'-dihydro derivatives under these conditions leads to analogous compounds. Reduction of the nitrobiquinolyls gives the respective amines. Acylation of the latter leads to acylamino-2,3'-biquinolyls.
