1-Bromo-4-methoxybutane (cas: 4457-67-4) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.Computed Properties of C5H11BrO

The physicochem. properties of room temperature ionic liquids (RTILs) consisting of bis(trifluoromethanesulfonyl)amide (TFSA–) combined with 1-hexyl-1-methylpyrrolidinium (Pyr1,6+), 1-(butoxymethyl)-1-methylpyrrolidinium (Pyr1,1O4+), 1-(4-methoxybutyl)-1-Me pyrrolidinium (Pyr1,4O1+), and 1-((2-methoxyethoxy)methyl)-1-methylpyrrolidinium (Pyr1,1O2O1+) were investigated using both exptl. and computational approaches. Pyr1,1O2O1TFSA, which contains two ether oxygen atoms, showed the lowest viscosity, and the relationship between its physicochem. properties and the position and number of the ether oxygen atoms was discussed by a careful comparison with Pyr1,1O4TFSA and Pyr1,4O1TFSA. Ab initio calculations revealed the conformational flexibility of the side chain containing the ether oxygen atoms. In addition, mol. dynamics (MD) calculations suggested that the ion distributions have a significant impact on the transport properties. Furthermore, the coordination environments of the Li ions in the RTILs were evaluated using Raman spectroscopy, which was supported by MD calculations using 1000 ion pairs. The presented results will be valuable for the design of functionalized RTILs for various applications. In the experiment, the researchers used many compounds, for example, 1-Bromo-4-methoxybutane (cas: 4457-67-4Computed Properties of C5H11BrO).
