Piperonal condenses best when heated without any other condensing reagent, with seven of the common amides, giving characteristic piperonyl-

The condensations of 6-nitropiperonal with amides have been studied. The products are in their properties in a line with the products obtained from piperonal itself. In the case of acetamide and cinnamamide the yields were distinctly higher than they were with piperonal: in other cases the reaction was distinctly slower and gave lesser yields.
