A series of compounds of p-Nitro ethyl benzoate [2],p-Nitro benzoic hydrazide [3], 1-phenyl-4-(p-nitrophenyl) thiosemicarbazide [4], 3-mercapto-4-phenyl-5- (p-nitro phenyl)-1,2,4- Triazole[5], 3-hydrazino -4-phenyl-5- (p-nitro phenyl)-1,2,4- Triazole [6], 3-( substituted benzylidene hydrazine)-4-phenyl-5- (p-nitro phenyl-2-yl)-1,2,4-triazole [7] and [8], 2-(substituted aryl)-3-(p-nitrophenyl)-2-yl)-2,3-dihydro-1,3-oxazpine-4,7-dione.[9] and [10], 2-(substituted aryl)-3-(p-nitrophenyl)-2-yl-2,3-benzo-1,3-oxazpine-4,7-dione [11] and [12], 2-(substituted aryl) –tetrazolo-1-yl)-[(3-hydrazino-4-phenyl)- 5-p-nitrophenyl)1,2,4-triazole ] [9], 2-substituted aryl-3~-[3-hydrazino—4-phenyl-5-(p-nitrophenyl)1,2,4-triazole]-2-yl-thiazolidin-4-one [15] and [16]. 2-(substituted aryl) –3-[3-hydrazino—4-phenyl-5-(p-nitrophenyl)1,2,4-triazole]-2-yl-imidazolidin-4-one [17]and [18] were prepared and the chemical structures of these compounds were characterized by FT-IR , 1H-NMR for some of them Uv/vis spectra , C.H.N analysis ), melting points and the purity was checked. Biological activity of these compounds was evaluated.
