| Abstract | ||||
| 3-Dimethyl amino-1-phenyl propenone, 3-Dimethyl amino-1-p-tolyl-propenone and 1-(4-Bromo phenyl)-3-dimethyl amino-propenone 4a-c were gotten in a good yields by reaction of methyl ketones (acetophenone, p-methyl acetophenone, p-bromo acetophenone) with dimethyl formamide dimethyl acetal DMFDMA in para-xylene. Enaminones 4a-c were exposed to coupling process with arylidene diazonium chloride to afford the disperse dyes 7a-f. The substance structures were explained by various diagnostic procedures as well as elemental analysis, Fourier-transform infrared spectroscopy (FT-IR), and nuclear magnetic resonance 1H-NMR spectra. These disperse dyes delivered of the coupling reaction has affirmed that these colors in the solid state they exists in the anti rather than syn-form. | ||||
