New Advances in Chemical Research, April 2021.18514-84-6. Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount. Introduce a common compound, CAS is 18514-84-6, Name is Cinnolin-4(1H)-one, belongs to cinnolinecompound.

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).
