    Abstract: Three Dialdehydes were synthesized by the reaction of Salicylaldehyde and many Aliphatic and Aromatic Halides. The optimal condition (Catalysts, Temperature, Time of Reaction and Effect of Solvents) to get a high selective compounds and high yields have been studied. The reactions were followed by using Thin Layer Chromatography (TLC). The synthesi... Show More
