875-66-1, Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.875-66-1, name is Cinnolin-4-ol, below Introduce a new synthetic route.
a. 4-Chloro-8-nitroquinoline (6a). This intermediate was prepared from 4-chloroquinoline (obtained by treating 4-hydroxyquinoline with [POC13] as [ DESCRIBED BY GOULEY, R. W., ET AL. , J. AMER. CHEM. SOC., 1947, 69, 303-306.4-] Chloroquinoline (10.0 g, 61.3 mmol) was added in small portions to sulfuric acid (45 mL) taking care to maintain the temperature at or below 15 C. Then the solution was cooled and maintained at-15 C during the addition of fuming nitric acid (9 mL). The mixture was allowed to warm to room temperature and stirred for an additional 3 hours. The reaction mix was poured on ice and basified (pH 9) with NH40H. The resulting precipitate was filtered, washed well with water, dried, and recrystallized from methanol to provide 7.5 g of 6a, in 59 % yield; m. p. = [128-129 C] (lit. m. p. = [129-130 C) ; IH] NMR [(CDC13)] [8] 7.67 (d, [1H,] J=4. 5), 7.75 (dd, 1H, J=8. 6 [HZ,] J=7. 6), 8.10 (dd, 1H, J=7. 6, J=1. 3), 8. 48 (dd, 1H,.

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 Cinnolin-4-ol, CAS: 875-66-1
