One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine. 20469-65-2, formula is C8H9BrO2, Name is 1-Bromo-3,5-dimethoxybenzene, Name: 1-Bromo-3,5-dimethoxybenzene
Weiss, Robin;Aubert, Emmanuel;Groslambert, Loic;Pale, Patrick;Mamane, Victor research published 《 Chalcogen Bonding with Diaryl Ditellurides: Evidence from Solid State and Solution Studies.》, the research content is summarized as follows. The chalcogen bonding (ChB) ability of Te is studied in sym. diaryl ditellurides ArTeTeAr, Ar = Ph, 3,4-(OMe)2C6H3, 3,5-(CF3)2C6H3, 2-CF3C6H4, 3,5-(Cl)2C6H3, 3,5-(t-Bu)2C6H3. Among the two Te σ-holes, the one along the less polarized Te-Te bond was calculated as the more electropos. This counter-intuitive situation is due to the hyperconjugation contribution from Te lone pair to the σ* of the adjacent Te which coincides with σ-hole along the more polarized Te-Ar bond. Diaryl ditellurides showed notable structural features in the solid state as a result of intermol. Te···Te ChB, such as a Te4 rectangle through dimer aggregation or a triangular Te3 motif, where one Te interacts with both Te atoms of a neighboring mol. through both its σ-hole and lone pair, in a slightly frustrated geometry. Lewis acidity of diaryl ditellurides was also evaluated by NMR with R3PO as σ-hole acceptors in different solvents. Thus, 125Te NMR allowed monitoring Te···O interaction and delivering association constants (Ka) for 1 : 1 adducts. The highest value of Ka=90 M-1 was measured for the adduct between diaryl ditellurides bearing CF3 groups and Et3PO in cyclohexane. Notably, by using nBu3PO, Te···O interaction was revealed by 19F-1H HOESY showing spatial proximity between CF3 and CH3 of nBu3PO.
Name: 1-Bromo-3,5-dimethoxybenzene, 1-Bromo-3,5-dimethoxybenzene, also known as 1-Bromo-3,5-dimethoxybenzene, is a useful research compound. Its molecular formula is C8H9BrO2 and its molecular weight is 217.06 g/mol. The purity is usually 95%.
1-Bromo-3,5-dimethoxybenzene is used as an intermediate in the synthetic preparation of pharmaceutical inhibitors via cross-coupling reactions.
1-Bromo-3,5-dimethoxybenzene can be synthesized by using 1,3-dimethoxybenzene via iridium-catalyzed arene borylation.
1-Bromo-3,5-dimethoxybenzene (1BDMB) is a synthetic molecule that can be used as an electron acceptor in organic photovoltaic cells. 1BDMB is a salt of the sodium salt of resorcylic acid and 1,3-dibromo-5,5-dimethoxybenzene. It has been shown to have a radical mechanism for the generation of free radicals. The radical mechanism is initiated by light absorption by the ruthenium complex at the center of the molecule which induces photoinduced electron transfer from the ruthenium to 1BDMB. This process results in electron transfer from the donor to an acceptor molecule, such as oxygen or nitrogen. The pharmacokinetic properties of this compound are not well known; however, it has been demonstrated that it can be synthesized through a cross-coupling reaction with other aromatic compounds such as stemofuran., 20469-65-2.
