followed by the reaction with thiourea, guanidine carbonate, and hydroxylamine hydrochloride gave the corresponding thienopyridine derivatives. The biological activity of some new compounds has been discussed.

To provide these fabrics practical qualities, we treated the colored polyester texture with dispersion dyes that we had previously produced. After treating the fabric with zinc oxide ZnO nano particle size NPs, the self-cleaning and light fastness were investigated and it was discovered that these properties were greatly enhanced. The polyester texture's capacity to shield against UV light has been tested.

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 1 H-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.
