As a common heterocyclic compound, it belongs to chiral-nitrogen-ligands compound, name is Tris[2-(dimethylamino)ethyl]amine, and cas is 33527-91-2, its synthesis route is as follows.
To a solution of tris(2-dimethylaminoethyl)amine (0.401 g, 1.74 mmol) in acetonitrile (4 mL) was added 1-bromododecane (1.34 g, 5.38 mmol). The resulting mixture was heated at reflux with stirring for 22 hours, during which time awhite 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 a Buchner funnel, and rinsed with a cold hexanes/acetone mixture (20 mL, 1:1), resulting in T-12,12,12 (1.39 g, 82%) as a white powder; mp=225-254 C; ?H NMR (300 JVII-Tz, CDC13) oe 4.11-4.03 (m, 6H), 3.63-3.55 (m, 6H), 3.39-3.32 (m, 6H), 3.30(s, 18H), 1.72-1.62 (m, 6H), 1.37-1.14 (m, 54H), 0.84-0.78 (m, 9H); ?3C NMR (75 MHz, CD3OD) 3 65.3, 61.0, 50.1, 46.8, 31.7, 29.4, 29.3, 29.3, 29.1, 29.0, 26.1, 22.4, 22.4, 13.1; high resolution mass spectrum (ESI) m/z 245.9435 ([Mj3 calculated for [C48H,o5N4j3: 245.9441).
