We report in this contribution the first photochemical study of benzene trapped solid nitrogen at low temperature (16 K) and irradiated with a mercury lamp (λ > 230 nm). identify three isomers (fulvene, Dewar benzvalene) two radicals (phenyl benzyne) as photo-dissociation products, along acetylene derivatives substituted benzene. present for time infrared spectrum fulvene ice, which is obtained...

Benzimidazole is a bicyclic heterocyclic aromatic compound in which benzene fused to imidazole moiety. holds vital role the field of medicinal chemistry possesses wide variety pharmacological activities like antibacterial, anti cancer, antifungal, antileishmanial, tubercular, viral and malarial respectively, hence benzimidazole moiety attracting chemist synthesize different derivatives with act...

The study of the polyfluorination and polytrifluoromethylation effects on electronic structure and intrinsic acidities has been performed using DFT B3LYP and NBO calculations for the valence isomers of benzene and phenol, i.e., the structures of prismane, benzvalene, Kekulé, and Dewar systems. Also the isodesmic reaction analysis approach to estimate the effects of the substituents on the acidi...

The crystal structure of the title compound, C(15)H(11)FN(2)O(3), was determined as part of a study on the biological activity of isoxazolone derivatives as p38 mitogen-activated protein kinase (MAPK) inhibitors. The dihedral angles between rings are isoxazole/benzene = 55.0 (3)°, isoxazole/pyridine = 33.8 (2)° and benzene/pyridine = 58.1 (2)°.
