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.
2-(2-methoxyphenyl)-1,3-dimethylimidazolidine. A solution of o-anisaldehyde (9.0 g, 66 mmol) and N,N’-dimethylethylenediamine (7.9 mL, 73 mmol) in ethanol (180 mL) was stirred at r.t. for overnight. MgSO4 (30 g) was added and the mixture was stirred for 20 min. The reaction mixture was filtered and washed with ether. The solvent was removed in vacuo to afford 2-(2-methoxyphenyl)-1,3-dimethylimidazolidine as a light yellow solid, 12 g, yield 88%. 1H NMR (500 MHz, CHLOROFORM-D) delta ppm 2.21 (s, 6H) 2.57-2.72 (m, 2H) 3.34 (d, J=2.75 Hz, 2H) 3.82 (s, 3H) 4.13 (s, 1H) 6.88 (d, J=8.24 Hz, 1H) 7.00 (t, J=7.48 Hz, 1H) 7.25-7.30 (m, 1H) 7.67 (d, J=7.63 Hz, 1H).
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
