Synthesis and Antimicrobial Activity of Some 2-[(4-Substituted-Phenyl-3-Chloro-Azetidin-2-One)-5-(2'-Methylamino-4-Phenyl-1', 3'-Thiazolyl-]-1, 3,4-Thiadiazoles
A new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. The synthesised compounds have been screened in vitro for their antimicrobial acti...
متن کامل4-(4-Bromophenylhydrazono)-1-(5-bromopyrimidin-2-yl)-3-methyl-2-pyrazolin-5-one
The asymmetric unit of the title compound, C(14)H(10)Br(2)N(6)O, contains two crystallographically independent mol-ecules. The pyrazole ring of one mol-ecule makes dihedral angles of 22.0 (3) and 3.5 (3)° with the pyrimidine and benzene rings, respectively; the corresponding values in the other mol-ecule are 9.2 (3) and 2.1 (3)°, respectively. The mol-ecules are linked by N-H⋯O, C-H⋯N and C-H⋯B...
متن کاملSynthesis, Characterization, and Chelating Properties of 4-nitrobenzoylsemicarbazone-1- Phenyl-3-methyl-2-pyrazolin-5-one (nbmp-sc)
4-Nitrobenzoylsemicarbazone-1-phenyl-3-methyl-2-pyrazolin-5-one (NBMP-SC) was prepared and its metal chelates of Cu,Ni,Co,Mn,Fe,Fe,Cr,UO2 and OV were prepared. The ligands and its chelates were characterized by elemental analysis, Metal: ligand (M:L) stoichiometry, IR-electronic spectral studies and magnetic properties. The compounds also were screened for their antimicrobial activity.

متن کامل1-[3-(2-Nitrophenyl)-5-phenyl-2-pyrazolin-1-yl]ethanone
The title compound, C(17)H(15)N(3)O(3), was prepared from 1-(2-nitro-phen-yl)-3-phenyl-prop-2-en-1-one and hydrazine. The dihedral angle between the benzene and phenyl rings is 74.55 (2)°. The pyrazoline ring is in a slight envelope conformation with the C atom bonded to the phenyl ring forming the flap. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds connect mol-ecules into...
