110-70-3, Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.110-70-3, name is N1,N2-Dimethylethane-1,2-diamine, below Introduce a new synthetic route.
beta-CD-OTs (500.0 mg, 0.388 mmol) was dissolved in 5 mL dry DMF with 100 mg NaI. N,N?-Dimethylethane-1,2-diamine (1.28 mL, 11.72 mmol) was then added under N2 and the reaction mixture was stirred overnight at 70 C. under N2. The next day the reaction mixture was cooled and precipitated in 50 mL acetone, giving a white precipitate. Unreacted tosylate was removed via the same ion-exchange methods as described above for beta-CD-NH2. Yield=374 mg (80.0%). 1H NMR (300 MHz, D2O, delta): 5.02-4.87 (s, 7H, C1H of CD), 3.93-3.64 (m, 29H, C2H, C3H, C4H, and C5H of CD and NH), 3.61-3.29 (m, 14H, C6H of CD), 3.01-2.36 (m, 10H, N1-CH2, N2-CH2, and N2-(CH3)2).
This molecular description is the mechanism of the reaction; it describes how individual atoms, ions, or molecules interact to form particular products.If you are interested, you can also browse other articles of N1,N2-Dimethylethane-1,2-diamine, We look forward to the emergence of more reaction modes in the future.
