Vinyl bromides undergo the Heck reaction, which involves C-C coupling with alkene to give substituted alkenes. 19111-87-6, formula is C18H11Br, Name is 2-Bromotriphenylene. Methyl bromide is a precursor in the manufacture of several chemicals and is employed as a soil sterilant, mainly for seed production. Category: bromides-buliding-blocks.
Jin, Rong;Liu, Guorui;Jiang, Xiaoxu;Liang, Yong;Fiedler, Heidelore;Yang, Lili;Zhu, Qingqing;Xu, Yang;Gao, Lirong;Su, Guijin;Xiao, Ke;Zheng, Minghui research published ã?Profiles, sources and potential exposures of parent, chlorinated and brominated polycyclic aromatic hydrocarbons in haze associated atmosphereã? the research content is summarized as follows. Profiles, sources, and potential exposures of chlorinated and brominated polycyclic aromatic hydrocarbons (ClPAH, BrPAH) in haze associated atm. remain unclear. Haze events occur frequently during the heating period in Beijing, China, and provide a typical urban context to assess concentrations, profiles, sources, and potential exposure to ClPAH, BrPAH, and their non-halogenated parent compounds (PAH) in air. Average PAH, ClPAH, and BrPAH concentrations during heating periods (with more frequent haze events) were â?-9 times higher than during non-heating periods. Particulate matter (PM)-associated ClPAH and BrPAH concentrations were higher in heating vs. non-heating periods; for gas-associated ClPAH and BrPAH, this distinction was not significant. Congener patterns and profiles indicated that with increasing coal combustion in the heating period, PAH and ClPAH concentrations in air were elevated vs. the non-heating period. Inhalation of PM-associated PAH, ClPAH, and BrPAH accounted for higher exposure than inhalation of gas phase and dermal contact of gaseous and particulate phases. Results determined the particulate phase is the dominant exposure pathway for atm. PAH, ClPAH, and BrPAH during haze events, which is different from previous studies.
Category: bromides-buliding-blocks, 2-Bromotriphenylene is a useful research compound. Its molecular formula is C18H11Br and its molecular weight is 307.2 g/mol. The purity is usually 95%.
2-Bromotriphenylene is a brominating agent that has the ability to react with sodium carbonate and emit light. The luminescence of 2-bromotriphenylene can be used as an indicator of the degree of dilution, or how much water is present in a solution. It also emits light when it reacts with chloride ions in a reaction solution. 2-Bromotriphenylene can be used as a polymer matrix to form polymeric films, which are then used as catalysts for organic reactions. The luminescence properties of 2-bromotriphenylene make it suitable for use in functional theory experiments. This chemical compound is relatively low cost, and has been shown to have high yield in catalysis., 19111-87-6.
