18514-84-6, 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.18514-84-6, name is Cinnolin-4(1H)-one. An updated downstream synthesis route of 18514-84-6 as follows.
Intermediate 2: Preparation of 3-Bromo-l,4-dihydro-4-cinnolinone:Bromine (0.8 ml) in acetic acid (10 ml) was added to a mixture of cinnolin-4- one (1.5 g, 10.27 mmol), sodium acetate (1.51 g, 18.49 mmol) and acetic acid (15 ml) maintained at 100 0C and stirred at that temperature for Ih. The mixture was concentrated under reduced pressure to half the initial volume and poured into water. The precipitated solid was filtered, washed with water and dried under reduced pressure. Yield: 64%. 1H-NMR (delta ppm, CDCl3, 300 MHz): 13.87 (br. s, IH); 8.06 (d, J = 7.8, IH); 7.84-7.80 (m, IH); 7.61 (d, J = 8.7, IH); 7.49 (t, J = 7.8, IH).
In every case, we must determine the overall rate law from experimental data and deduce the mechanism from the rate law (and sometimes from other data). you can also browse my other articles about Cinnolin-4(1H)-one, CAS: 18514-84-6, if you are interested.
