m-terphenyls were obtained by the rearrangement of quaternary nitropyridiniumsalts under the action of aqueous alcoholic alkali and aqueous methylamine. Hantzsch 4-aryl-2-methyl-5-nitro-6-phenyl-1,4-dihydropyridines obtained by the cyclocondensation of nitrochalcones with various enamines were used as starting compounds. The oxidation of 1,4-dihydropyridines with sodium nitrite in acetic acid gave
