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.110-70-3, N1,N2-Dimethylethane-1,2-diamine it is a common compound, a new synthetic route is introduced below.110-70-3
Step. A: N-Methyl-N’-methyl-N’-t-butoxycarbonylethylenediamine A solution of 1 gram (4.58 mmole) of di-t-butyl-dicarbonate in 8 mL of CH2 Cl2 at 0 C. was treated with 0.98 mL (9.16 mmole) of N-methyl-N’-methylethylenediamine. After 20 min the cooling bath was removed and the mixture allowed to warm to 22 C. After 4 hours the mixture was concentrated in vacuo. The residue was purified by flash chromatography on 68 g silica gel eluding with 1 liter of 100:9:0.3 CH2 Cl2:MeOH: ammonia water, then 500 mL of 100:11:0.3 CH2 Cl2:MeOH: ammonia water to give 190 mg (22%) of a volatile oil.
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
