SELENIUM HETEROCYCLES XXXX [I] SYNTHESES OF 4- (2-PYRAZINYL) - 1, 2, 3: SELENADIAZOLE AND 4- (2-PYRAZILYL)' - l,2,3- THIADIAZOLE
Reaction of thionyl chloride with 2-acetyl-1- benzenesulfonylpyrrole semicarbazone (6 c) gave 4 - (1- benzenesulfonyl-2 - pyrrolyl) - 1, 2, 3 -thiadiazole (lc). Selenium dioxide oxidation of 2-acetylpyrazine semicarbazone (10) in acetic acid afforded 4- (2-pyrazinyl) - 1, 2, 3- selenadiazole (4). Reaction of thionyl chloride with compound 10 gave 4- (2-pyrazinyl) - 1, 2, 3- thiadiazole (3)....

In a search for new leads towards potent antimicrobial agents, an array of novel (2E)-ethyl-2-(2-(2,4-dinitrophenyl)hydrazono)-4-(naphthalen-2-yl)-6-arylcyclohex-3-ene carboxylates 17-24 were synthesized and characterized through their melting point, elemental analysis, MS, FT-IR, one-dimensional NMR (1H, D2O exchanged 1H and 13C), two dimensional HOMOCOR and HSQC spectroscopic data. In-vitro m...

متن کامل2-(4-Fluorophenyl)-2-oxoethyl 4-methoxybenzoate
In the title compound, C(16)H(13)FO(4), the dihedral angle between the benzene rings is 84.28 (8)°. In the crystal, C-H⋯F and C-H⋯O hydrogen bonds link the mol-ecules to form a three-dimensional network. The crystal structure is consolidated by C-H⋯π inter-actions and short F⋯F contacts [2.7748 (14) Å] also occur.
متن کامل2-(4-Bromophenyl)-2-oxoethyl 4-chlorobenzoate
The asymmetric unit of the title compound, C(15)H(10)BrClO(3), consists of three crystallographically independent mol-ecules. The dihedral angles between the benzene rings in the three mol-ecules are 68.8 (2), 0.7 (3) and 66.1 (2)°. In the crystal, the three independent mol-ecules are inter-connected by C-H⋯O hydrogen bonds, leading to isolated trimers.
