The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Tris[2-(dimethylamino)ethyl]amine, cas is 33527-91-2,the chiral-nitrogen-ligands compound. Here is a downstream synthesis route of the compound., 33527-91-2
To a solution of tris(2-dimethylaminoethyl)amine (0.436 g, 1.89 mmol) in acetonitrile (4 mL) was added 1-bromooctane (1.20 g, 6.22 mmol). The resulting mixture was heated at reflux with stirring for 18 hours, during which time a white solid was observed. After cooling, and the addition of a cold hexanes/acetone mixture (15 mL, 1:1), to the reaction flask, the precipitate was filtered with aBuchner funnel, and rinsed with a cold hexanes/acetone mixture (20 mL, 1:1), resulting in T-8,8,8 (1.45 g, 95%) as a yellow-white wax; ?H NMR (300 MI-Tz, CDC13) oe 4.02-3.94 (m, 6H), 3.63-3.54 (m, 6H), 3.42-3.30 (m, 24H), 1.79-1.67 (m, 6H), 1.41-1.19 (m, 30H), 0.90-0.83 (m, 9H); ?3C NMR (75 MHz, CD3OD) oe 65.3,61.0, 50.1, 46.8, 31.5, 28.9, 26.1, 22.4, 22.3, 13.1; high resolution mass spectrum(ESI) m/z 189.8823 ([Mj3 calculated for [C36H8,N4j3: 189.8815). See also Yoshimura et al., 2012, Langmuir 28:9322-933 1. ?H and ?3C NMR spectra of compound T-8,8,8 can be found in Figure 49.
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
