110-70-3, 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. N1,N2-Dimethylethane-1,2-diamine, cas is 110-70-3,the chiral-nitrogen-ligands compound, it is a common compound, a new synthetic route is introduced below.
To a stirred solution of Lambda/,Lambda/’-dimethylethylene diamine (3.66 mL, 34 mmol) in dichloromethane (40 mL) at 0C was added dropwise a solution of di-tert-butyl dicarbonate (2.4 g, 11 mmol) in dichloromethane (20 mL) and allowed to warm to room temperature overnight, concentrated under reduced pressure, diluted with EtOAc (100 mL), washed with water (2 * 100 mL), brine (100 mL), dried and concentrated under reduced pressure to give the title product 91 as a colourless oil (1.54 g, 74% yield). 1H NMR (400 MHz, CDCI3) delta 3.26 (t, J = 6.15 Hz, 2H), 2.81 (s, 3H), 2.66 (t, J = 6.57 Hz, 2H), 2.38 (s, 3H), 9.28 (s, 9H) ppm.
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 N1,N2-Dimethylethane-1,2-diamine, 110-70-3
