Synthesis, Structural And Theoretical Investigation of Some New Schiff Bases And 1,3,4-oxadiazole Compounds Derived from Lauric Acid

New Schiff bases derivatives from lauric acid were synthesized through the condensation of dodecane methyl ester with hydrazine to give corresponding hydrazide, which react aromatic aldehyde afford dodecanehydrazide-hydrazones and carbon disulfide 1,3,4-oxadiazole-2-thion. The chemical structures confirmed by numerous characterization methods; including Infrared, Ultraviolet-Visible, 1H 13C Nuclear Magnetic Resonance (NMR) measurements. In order investigate Resonance, vibrational frequencies, Ultraviolet visible spectra, optimized molecular geometry, HOMO & LUMO other spectroscopic properties, Density Functional Theory (DFT/B3LYP/6-311++G(d,p)) stimulations carried out
