Synthesis and Characterization of Seven Membered Heterocyclic Derivatives from Chalcone Compounds.

Abstract

The aim is to synthesize and characterized heterocyclic compounds and study their thermal stability as a step for future work. A preparation of chalcones synthesized warred out by mixing equal acetophenone with aldehydes. The second step (synthesized of 7- rings) was performed by reacting the chalcones with aliphatic diamines . The results showed obtaining of 7- membered heterocyclic compounds, these compounds are charted using FT-IR, 1H-NMR, 13C NMR, and TGA (thermal stability). The TGA analysis shows the thermal stability of compound TGA peak appeared at a temperature certain this is an indication that the compound is thermally stable at this temperature.
