    • Abstract


      Malonanilic acid have been condensed under different conditions, with 6-nitro-piperonal, 6-bromopiperonal, 5-bormovanillin and 5-bromoveratraldehyde. The reactions with the first two give yields that may be more or less expected. The last two give some unexpected features, particularly 5-bromoveratraldehyde from which the expected cinnamanilide has not yet been isolated or obtained. All the products described in the paper are new.
