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, Quality Control of 20469-65-2
Ritchie, Nina F. C.;Zahara, Adam J.;Wilkerson-Hill, Sidney M. research published 《 Divergent Reactivity of α,α-Disubstituted Alkenyl Hydrazones: Bench Stable Cyclopropylcarbinyl Equivalents》, the research content is summarized as follows. The divergent reactivity of 2,2-dialkyl-3-(E)-alkenyl N-tosylhydrazones using Pd-catalyzed cross-coupling conditions, which enabled the Z-selective synthesis of 3-aryl-1,4-dienes and gem-dialkyl vinylcyclopropanese. It was found that the dialkylbiaryl phosphine ligand SPhos was the optimal ligand for this transformation producing skipped dienes in up to 83% isolated yield. The ratio of skipped diene to vinylcyclopropane was dependent on both the structure of the α,α-disubstituted hydrazones and the aryl halide component. Using sterically encumbered aryl bromides provided the trans-cyclopropane products selectively in up to 69% yield. The reaction was stereospecific and stereoselective and occurs alongside a competing 1,2-vinyl group migration pathway.
Quality Control of 20469-65-2, 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.
