Adding some certain compound to certain chemical reactions, such as: 764-48-7, name is Ethylene Glycol Vinyl Ether, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 764-48-7. 764-48-7
Intermediate 2; O-(2-(vinyloxy)ethyl)hydroxylamine; Step A: 2-(2-(vinyloxy)ethoxy)isoindoline-1,3-dione To a solution of 2-(vinyloxy)ethanol (20.4 mL, 227 mmol), triphenylphosphine (59.5 g, 227 mmol), and N-hydroxyphthalimide (37.0 g, 227 mmol) in THF (450 mL) was added DEAD (35.9 mL, 227 mmol) at 0 C. under a N2 atmosphere. After stirring for 16 h at room temperature, the reaction mixture was concentrated in vacuo. The residue was filtered, washed with chloroform and the filtrate was concentrated in vacuo. The residue was purified by column chromatography on SiO2 (Hex: EtOAc=2:1) to give 2-(2-(vinyloxy)ethoxy)isoindoline-1,3-dione (32.5 g, 61.4%) as a yellow solid. 1H NMR (CDCl3, Varian 400 MHz) delta 4.04-4.08 (3H, m), 4.19 (1H, dd, J=14.4, 2.2 Hz), 4.45-4.48 (2H, m), 6.47 (1H, dd, J=14.0, 6.8 Hz), 7.53-7.78 (2H, m), 7.80-7.87 (2 m, m).
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 764-48-7.
