69778-83-2, A balanced equation for a chemical reaction indicates what is reacting and what is produced, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.69778-83-2, name is 4-Methoxy-1H-pyrrol-2(5H)-one. An updated downstream synthesis route of 69778-83-2 as follows.
Example 1 Compound (VII) To a solution of 2-formyl-5-undecylpyrrole (4 g; 16.03 mmols) and 4-methoxy-3-pyrrolin-2-one (3.63 g; 32.06 mmols) in DMSO (53 ml) 2N sodium hydroxyde (45 ml) is added under nitrogen atmosphere and the mixture is stirred at 60¡ã C. for 8 hours. After dilution with water (200 ml) the yellow suspension is extracted with dichloromethane (600 ml). The organic phase is shacked with water and brine, anhydrified over anhydrous sodium sulphate and evaporated to dryness. The crude material is taken up in hexane and filtered to give 4-methoxy-5-(5-undecyl-1H-pyrrol-2-yl-methylene)-1,5-dihydro-pyrrol-2-one (4.86 g; 14.11 mmols) as a yellow crystalline solid. Yield: 88percent. 1 NMR (400 mhz, CDCl3), ppm: 0.87 (3H, m), 1.2-1.5 (16H, m), 1.72 (2H, m), 2.73 (2H, m), 3.89 (3H, s), 5.08 (1H, d, J=1.7 Hz), 5.97 (1H, dd, J=2.4 and 3.2 Hz), 6.31 (1H, s), 6.36 (1H, t, J=3.2 Hz), 10.25 (1H, bs), 10.74 (1H, bs)., 69778-83-2
There are, however, a few established termolecular elementary reactions. The reaction of nitric oxide with oxygen appears to involve termolecular steps. you can also browse my other articles about 69778-83-2
