It is a common heterocyclic compound, the chiral-nitrogen-ligands compound, Tris[2-(dimethylamino)ethyl]amine, cas is 33527-91-2 its synthesis route is as follows.
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.
