52997-43-0, Adding some certain compound to certain chemical reactions, such as: 52997-43-0, name is 7-(Bromomethyl)pentadecane, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 52997-43-0.
General procedure: General procedure for the synthesis of a1-a6: To a solution of indoline-2,3-diones (10 mmol) in DMF (40 mL) was added K2CO3(15 mmol, 2.073 g) and 7-(bromomethyl)pentadecane (11 mmol,3.358 g) under nitrogen. The mixture was stirred at 70 C and monitoredby TLC. After the reaction completed, water was added, andextracted with EtOAc. The organic layer was combined and dried withMgSO4. After evaporation of the solvent, the residue was purified bycolumn chromatograph (eluent: Petroleum/EtOAc=20:1) to give thetarget compound. 1-(2-Hexyldecyl)indoline-2,3-dione (a1) Orange oil, 3.46 g, 93%.FT-IR (KBr) nu=1743 and 1612 cm-1 (C]O). 1H NMR (400 MHz,CDCl3) delta 7.60-7.55 (m, 2H), 7.10 (dd, J1=7.2 Hz, J2=7.6 Hz, 1H),6.86 (d, J=8.0 Hz, 1H), 3.59 (d, J=7.2 Hz, 2H), 1.86-1.81 (m, 1H),1.34-1.23 (m, 24H), 0.88-0.83 (m, 6H); 13C NMR (100 MHz, CDCl3) delta183.28, 158.19, 151.21, 138.20, 124.90, 123.32, 117.29, 110.30,44.42, 35.78, 31.64, 31.54, 31.27, 29.73, 29.40, 29.29, 29.06, 26.12,26.09, 22.44, 22.41, 13.88, 13.84. ESI-MS(100%, negative) m/z=371.2 (M-).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 52997-43-0.
