We report here the experimental and theoretical investigation of bis(4-furoyl-3-methyl-1-phenyl-2-pyrazolin-5-one)oxoperoxomolybdenum(VI) complex molecule. It was prepared by reaction (2:1) 4-furoyl-3-methyl-1-phenyl-2-pyrazolin-5-one [MoO(O)2]2+ in an aqueous ethanol medium. Characterization performed elemental analysis, molar conductivity, magnetic measurements, electrochemical infrared elect...

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...

New efficient synthetic methods in pyrazoline and pyrazolopyrazine chemistry have been developed starting from 2,2-dichlorovinylacetophenones 1, which were sequentially transformed into 3-aryl-5-dichloromethyl-1-(2-hydroxiethyl)-2-pyrazolines 2, 3-aryl-5-dichloromethyl-1-(2-O-tosylhydroxyethyl)-2-pyrazolines 3, 3-aryl-5-dichloromethyl-1-(2-azidoethyl)-2-pyrazolines 4, 3-aryl-5-dichloromethyl-1-...

The title spiro-oxindole compound, C(26)H(23)N(3)O(3), was prepared by the reaction of isatin, 3-methyl-1-phenyl-2-pyrazolin-5-one and 5,5-dimethyl-cyclo-hexane-1,3-dione in an ethanol solution. The fused cyclo-hexene ring adopts an envelope conformation. The dihedral angle between the aromatic and pyrazoline rings is 23.70 (8)°. An intra-molecular C-H⋯O inter-action occurs. The crystal structu...
