33527-91-2, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Tris[2-(dimethylamino)ethyl]amine, cas is 33527-91-2,the chiral-nitrogen-ligands compound, it is a common compound, a new synthetic route is introduced below.
To a solution of tris(2-dimethylaminoethyl)amine (0.426 g, 1.85mmol) in acetonitrile (4 mL) was added 1-bromodecane (1.27 g, 5.73 mmol). Theresulting mixture was heated at reflux with stirring for 18 hours. After cooling, and the addition of hexanes (5 mL), a white solid precipitated, which was filtered with a Buchner funnel, transferring with a cold hexanes/acetone mixture (15 mL, 1:1). The solid was rinsed with a cold hexanes/acetone mixture (2O mL, 1:1), resulting in T10 10,10,10 (1.16 g, 70%) as a white powder; mp=223-248 C; ?H NMR (300 MHz,CDC13) oe 4.11-4.02 (m, 6H), 3.62-3.53 (m, 6H), 3.41-3.27 (m, 24H), 1.72-1.62 (m, 6H), 1.38-1.14 (m, 42H), 0.85-0.78 (m, 9H); ?3C NMR (75 MHz, CD3OD) oe 65.4,61.1, 50.2, 46.9, 31.6, 29.2, 29.0, 28.9, 26.1, 22.4, 22.3, 13.0; high resolution mass spectrum (ESI) m/z 217.9095 ([Mj3 calculated for [C42H93N4j3: 217.9128). See alsoYoshimura et al., 2012, Langmuir 28:9322-9331. ?H and ?3C NMR spectra of compound T-10,10,10 can be found in Figure 50.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of Tris[2-(dimethylamino)ethyl]amine, 33527-91-2
