Abstract
An unusual product, resulted from the reaction of 5-nitro-2-furaldehyde with pyridine or its equivalents in acetic anhydride, was established to be 1, 2-diacetoxy-1, 2-bis (5-nitro-2-furyl) ethene.Similarly, 1, 2-diacetoxy-1, 2-bis (5-nitro-2-thienyl) ethene was obtained from the self-condensation reaction of 5-nitro-2-thenaldehyde. Attempts to prepare the corresponding condensation products of some other aromatic aldehydes, however, failed under the similar reaction conditions.
