MICROWAVE ASSISTED and TRADITIONAL SYNTHESIS andCHARACTERIZATION of 2-ALLYL-6,6 -[(3,3 -DIMETHOXY[1,1 -BIPHENYL]-4,4 - DIYL)BIS(NITRILOMETHYLIDYNE)]BIS-PHENOL and EXPERIMENTAL and THEORETICAL INVESTIGATION of ITS TAUTOMERIC PROPERTIES

34270

Schiff base compound 2-allyl-6,6 -[(3,3 -dimethoxy[1,1 -biphenyl]-4,4 - diyl)bis(nitrilomethylidyne)]bis-phenol (3) was synthesized using traditional heating and microwaveirradiation method with the condensation reaction of 3-allylsalicylaldehyde (1) and o-dianisidine (2). The chemical structure of compound (3) was characterized by elemental analysis, FTIR, 1H NMR and 13C NMR techniques. The tautomeric equilibria (for phenol-imine O-H...N and keto-amine O... H-N tautomers) in various organic solvents were studied using UV-visible region spectrophotometric method and keto-amine percentages were calculated. Furthermore, the geometry of compound, the energies of phenol-imine and keto-amine tautomers in different organic solvents, intramolecular O-H...N and O...HN hydrogen bond length, UV-visible excitation energy and oscillator strength were calculated with the theoretical calculation method DFT (B3LYP)/6-311+G(d,p) and calculations were compared with experimental results.
