Abstract
Process for obtaining 5-nitro-2-furfural-acylhydrazones, characterized by reacting benzalhydrazones or ketone hydrazones with acid anhydrides or acid chloraros in the presence of inorganic to organic bases, obtaining benzal-acylhydrazones or ketone-acylhydrazones which they are combined with 5-nitro-2-furfuraldehyde or its gem diacetate, in an alcoholic or aqueous alcoholic medium at temperatures between 20-80ºC.
