Abstract:New compounds of 5-(p-florophenyl)- 2-amino-1,3,4-thiadiazole [2], 2-(substituted benzylidene)-1,3,4-Thiadiazole -5-(p-florophenyl [3-10], 2-( substituted amino phenyl)- 1,3,4-Thiadiazole -2-yl)- )imidazolidine-4-one-3-[5-(p-florophenyl ] [11-18],Schemes 1, 2 and (E)-3(3(4-nitro or 4-N,N-dimethyl aminophenyl) acryloyl)-(3--nitrophenyl)[19,20], 3-(6-p-Nitrophenyl orp-N,N-Dimethylaminophenyl)-2-thioxo-1,2,5,6-tetrahydropyrimidine-4-yl)-(Nitrophenyl) [21,22], 3(5-4(3-nitrophenyl)-1-phenyl 4,5-dihydro-1H-pyrazol-3-yl)phenyl)-4-nitrophenyl or 4-N,N-Dimethyl aminophenyl): [23,24] and 3-(2-amino-4-(4-Nitrophenyl or 4-N,N-Dimethylaminophenyl)-5,6-dihydro-2H-1,3-oxazine-6-yl)-3-Nitrophenyl[25,26]have been synthesized. The prepared compounds have synthesized from chalcone [19,20]. The structures of these compounds were identified by FT-IR,H-NMR,Uv spectra and checked by TLC
