Abstract
Selected unsaturated, aromatic, and heterocyclic dialdehydes reacted with 1,3-bis(dimethylamino)trimethinium perchlorate in acetic anhydride in the presence of acid. One of the aldehyde group participated in the condensation, whereas the other was transformed into the diacetate. The obtained substituted methylenemalonaldehydes were characterized by their 1H NMR, IR, and mass spectra.
