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.
EXAMPLE 12 N-Boc-N,N’-dimethylethylene diamine N,N’-dimethyl ethylenediamine (8.8 g) was dissolved in 200 ml tetrahydrofuran and to this was added over a 10 min period di-t-butyldicarbonate (4.36 g) in 30 mL tetrahydrofuran. 72 hours later, the solvent was evaporated and the residue partitioned between ether and KHCO3 and the organic layer was dried (MgSO4) and evaporated to give 11.6 g title compound (58% yield). 300 MHz 1 H NMR was consistent with proposed structure.
The chemical industry reduces the impact on the environment during synthesis,110-70-3,N1,N2-Dimethylethane-1,2-diamine,I believe this compound will play a more active role in future production and life.
