Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 136630-39-2, Name is 2,7-Dibromo-9H-carbazole, molecular formula is , belongs to benzoxazole compound.

Benzoxazole and dioxolane substituted benzimidazole-based N-heterocyclic carbene-silver( I) complexes: Synthesis, structural characterization and in vitro antimicrobial activity
A novel series of 1,3-benzoxazole and 1,3-dioxolane substituted benzimidazole-based N-heterocyclic carbene (NHC) precursors (6a-b and 11a-b) and their corresponding NHC-silver(I) acetate (12a-b and 14a-b) and bis-NHC-silver(I) hexafluorophosphate complexes (13a-b and 15a-b) were synthesized and characterized by H-1 NMR, C-13 NMR, ATR-IR spectroscopic methods and elemental analysis techniques. Also, the molecular structure of benzimidazolium salt (6a) and bis-NHC-silver(I) hexafluorophosphate complex (13b) were unambiguously established by single crystal X-ray diffraction analysis. Fascinatingly, bis-NHC-silver(I) hexafluorophosphate complex (13b) was revealed to be dinuclear in nature. All the azolium salts (6a-b and 11a-b) as well as the corresponding silver(I) complexes (12a-b, 13a-b, 14a-b and 15a-b) were evaluated for their antimicrobial potential against Gram positive (Staphylococcus aureus), and a set of Gram negative (Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa) bacterial strains and two fungi, Candida albicans and Cryptococcus neoformans. Antimicrobial studies revealed the comparable activities of benzimidazolium salts (6a-b and 11a-b) and the silver(I) complexes (12a-b, 13a-b and 15a-b). Whereas, the 1,3-dioxolane substituted benzimidazole-based silver(I) acetate complexes (14a-b) demonstrated excellent potentials with both bacterial and fungal growth inhibition above 95%.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 136630-39-2, in my other articles.
