    • Abstract

       

      Salicylaldehyde-amide condensations always produced the salicylidene-monoamides and the highest yield was always obtained in the presence of pyridine.7 The 5-chlorosalicylaldehyde and the 3 ∶ 5-dichlorosalicylaldehyde gave the best yield usually when heated alone; the product was almost always the-bis in the case of the latter, and generally so in the case of the former. The condensations with cinnamamide gave a quicker and a higher yield, it being quantitative in the case of the dichlorosalicylaldehyde. As before a temperature slightly higher than that of the water-bath produced generally a better yield in the last two amide condensations.
