Abstract
Phosphorus pentasulfide reacts with the amides and substituted amides of 5-nitrofuran-2-carboxylic and 3-(5′-nitrofuryl-2′) acrylic acids in ethyl acetate to give the corresponding thioamides. Some amides of 5-nitrofuran-2-carboxylic and 3-(5′-nitrofuryl-2′) acrylic acids are synthesized for the first time. Iodine oxidation of 5-nitrofuran-2-thiocarboxamide gives 3, 5-bis (5′-nitrofuryl-2′)-1, 2, 4-thiazole.
