Abstract:
In this study, 2-hydroxy-5-methylbenzaldehyde was reacted with 2-amino-5-methylphenol, 2-amino-4-nitrophenol, 5-amino-2-methylphenol, 3,4-dimethoxybenzylamine, 3-chloro-4-methylaniline, 2-aminobenzonitrile, 2-methyl-3-nitroaniline, 4-methylaniline, 4-(trifluoromethyl)aniline and 3,5-difluoroaniline to give the corresponding  azomethine compounds. The synthesized compounds  are (Z)-6-(((2-hydroxy-4-methylphenyl)amino)methylene)-4-methylcyclohexa-2,4-dien-1-one,  (Z)-6-(((2-hydroxy-5-nitrophenyl)amino)methylene)-4-methylcyclohexa-2,4-dien-1-one, (Z)-2-(((3-hydroxy-4-methylphenyl)imino)methyl)-4-methylphenol, (E)-2-(((3,4-dimethoxybenzyl)imino)methyl)-4-methylphenol, (E)-2-(((3-chloro-4-methylphenyl)imino)methyl)-4-methylphenol, (E)-2-((2-hydroxy-5-methylbenzylidene)amino)benzonitrile, (E)-4-methyl-2-(((2-methyl-3-nitrophenyl) imino)methyl)phenol,  (E)-4-methyl-2-((((2-methyl-3-nitrophenyl)imino)methyl) phenol, (E)-4-methyl-2-(((4-methylphenyl)imino)methyl)phenol, (E)-4-methyl-2-((((4-(trifluoromethyl) phenyl)imino)methyl)phenol and (E)-2-(((3,5-difluorophenyl) imino)methyl)-4-methylphenol. The structures of these synthesized azomethine compounds were determined by IR, 1H-NMR, 13C-NMR and UV-Vis spectroscopic techniques.The crystallographic and molecular structures of the azomethine compounds,which single crystalls had been prepared in suitable solvents, were also determined by X-Ray diffraction method.
