Interaction of an oxadiazole derivative, 5-(3,4-dimethoxyphenyl)-3-(3-methoxyphenyl)-1,2,4-oxadiazole (DPMO) with Ag/Au/Cu and graphene quantum dots different solvents, is reported theoretically. The adsorption energy maximum for the Cu6 cluster minimum Ag6 cluster. asymmetric charge redistribution between DPMO M6s produces improvement in dipole moment values. decrease gaps complexes increased ...

A new series of 2-substituted-5-[2-(2-halobenzyloxy)phenyl]-1,3,4-oxadiazoles was designed and synthesized as anticonvulsant agents. Electroshock and pentylenetetrazole-induced lethal convulsion tests showed that the introduction of an amino group at position 2 of 1,3,4-oxadiazole ring and a fluoro substituent at ortho position of benzyloxy moiety had the best anticonvulsant activity. Our resul...

As a part of our ongoing research in the exploration of novel antimicrobial agents, we report herein novel synthesis of hybrid molecules 4-methyl-7-(2-oxo-2-(5-(substitutedthio)-1,3,4oxadiazol-2-yl)ethoxy)-2H-chromen-2-ones and 4-substitutedbenzylidene-3-methyl-1-(2-((4methyl-2-oxo-2H-chromen-7-yl)oxy)acetyl)-1H-pyrazol-5(4H)-ones by combining coumarin ring with 1,3,4-oxadiazole and pyrazole sc...

In the title compound, C(18)H(13)BrN(4)O(3)S(3), the tetra-hydro-pyridine ring adopts a half-chair conformation with the central methyl-ene-C atom of the NCH(2)CH(2) unit at the flap. The dihedral angles between the tetra-hydro-pyridine ring and the pyridine and two thio-phene rings are 69.34 (13) 5.66 (13) and 68.63 (13)°, respectively, while the dihedral angle between the 1,3,4-oxadiazole and...

A structure-property study across a series of donor-acceptor-donor structures composed of mono- and bi-(1,3,4-oxadiazole) units symmetrically substituted with alkyl functionalized bi-, ter- and quaterthiophene segments is presented. Synthetically tailoring the ratio of electron-withdrawing 1,3,4-oxadiazole to electron-releasing thiophene units and their alkyl grafting pattern permitted us to sc...

The S-(5-aryl-1,3,4-oxadiazol-2-yl) O-alkyl carbonothioate (4-9) and the alkyl 2-((5-aryl-1,3,4-oxadiazol-2-yl)thio) acetate (10-15) were synthesized by interaction of 5-aryl-1,3,4-oxadiazole-2-thiones with esters chloroformic acid chloroacetic acid. yields target compounds (7-9) obtained isobutyl chloroformate 69-73%, (4-6) propyl - 74-79% 86-92%, respectively. structures confirmed IR, UV, 1H ...
