N1,N2-Dimethylethane-1,2-diamine, cas is 110-70-3, it is a common heterocyclic compound, the chiral-nitrogen-ligands compound, its synthesis route is as follows.
A 100-mL single-neck round-bottomed flask equipped with a magnetic stirrer was purged with nitrogen, charged with N1,N2-dimethylethane-l,2-diamine (Ii) (1.61 g, 18.2 mmol), ethanol (5 mL) and Ih (500 mg, 1.82 mmol), and the reaction was stirred at room temperature for 1 h. After this time, the reaction mixture was evaporated under reduced pressure, and the resulting residue was purified by flash column chromatography to afford an 89% yield (404 mg) of Ij as a yellow oil: 1H NMR (500 MHz, DMSO-J6) 5 8.18 (d, 2H, J= 8.5 Hz), 7.60 (d, 2H, J= 8.5 Hz), 3.87
With the rapid development of chemical substances, we look forward to future research findings about 110-70-3
