Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 19155-24-9, name is 3,3-Dimethylindolin-2-one, This compound has unique chemical properties. The synthetic route is as follows., Computed Properties of C10H11NO
5-bromo-1,3-dihydro-3,3-dimethyl-2H-indol-2-one 3,3-dimethyl-indol-2-one (0.65 g, 4.03 mmnol) and sodium acetate (0.33 g, 4.07 mmol) were stirred in acetic acid (5 cm3) then bromine (0.66 g, 4.13 mmol) in acetic acid (5 cm3) was added drop-wise to the reaction mnixture. The reaction was stirred for 50 min., and then poured into water. The mixture was basified with sodium carbonate and then extracted with ethyl acetate (*3), dried (MgSO4), filtered, and evaporated to the title compound (0.89 g, 92percent) 1H NMR (DMSO-d6) delta 1.21 (s, 6H), 6.76 (d, 1H, J=8.22 Hz), 7.29 (dd, 1H, J=2.12 Hz, 8.23 Hz), 7.49 (d, 1H, J=2.03 Hz), 10.4 (s, 1H).
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 19155-24-9.
