Abstract
5-Formyl-5′-nitro-2,2′-dithienyl and 5-formyl-3′-nitro-2,2t'-dithienyl were obtained by nitration of 5-formyl-2,2t'-dithienyl with copper nitrate in acetic anhydride. The structures of the nitroaldehydes were established by their oxidation to the corresponding nitro acids of the 2,2′-dithienyl series, the decarboxylation of which yielded 5-nitro- and 3-nitr o-2,2′ -dithienyls.
