When developing chemical systems it’s of course important to gain a deep understanding of the chemical reaction process. 875-66-1. In an article, Which mentioned a new discovery about875-66-1 Name is Cinnolin-4-ol.
Cinnolin-4(1H)-one (5.0 g, 34.24 mol) was added to the K2CO3 ( 7.08 g, 51.36 mol) and 3- bromoprop-1-yne (3.11 mL, 41.09 mol) in ACN (20 mL) and the mixture stirred at 80 C for 4-8 h then reaction mixture was cool to rt. The mixture was concentrated, diluted with H2O (30 mL), and extracted with EtOAc (3 × 50 mL). The combined organic layers were dried (MgSO4), filtered and concentrated. Flash chromatography gave 4-(prop-2-yn-1-yloxy)cinnoline (13a). Synthesis of 4-(prop-2-yn-1-yloxy)cinnoline (4a). Yield (2.60 g, 65.5%). m.p. 100-110 C. Colourless solid.1H NMR (400 MHz, CDCl3) delta 8.34 (dd, J = 1.2, 1.2 Hz, 1H, Ar), 7.81-7.77 (m, 2H, Ar), 7.60 (d, J = 8.8 Hz, 1H, Ar), 7.46 (t, J = 8.0 Hz,1H, Ar), 5.14 (d, J = 2.4 Hz, 1H, -OCH2), 2.51 (t, J = 2.4 Hz, 1H, Alky). 13C NMR (100 MHz, CDCl3) delta 171.2, 140.6, 140.1, 134.0, 126.0, 125.2, 124.6, 115.1, 76.0, 75.7, 46.2. ESI-MS: m/z 185.27 [M+H]+. Anal. Calc. (C11H8N2O) C: 71.73; H: 4.38; N: 15.21. Found C: 71.80; H: 4.04; N: 15.28%.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In the meantime we’ve collected together some recent articles in this area about 875-66-1 to whet your appetite. Happy reading! 875-66-1
