Formula: C8H7NO, Modeling chemical reactions helps engineers virtually understand the chemistry, optimal size and design of the system, and how it interacts with other physics that may come into play.
Sodium hydride (9.0 g; 0.2 mol, 60% in mineral oil) was added portion-wise to a solution of oxindole (10.0 g, 75 mmol) in of dry DMF (350 mL). After 15 minutes, the reaction was cooled to 0 C. and 1,4 dibromoethane in 100 mL of dry DMF was added over 15 minutes. The dark brown reaction was allowed to warm to room temperature and stirred overnight. The reaction was diluted with ethyl acetate and water was added. The layers were separated and the organic layer was dried over anhydrous sodium sulfate. The organic layer was filtered, concentrated in vacuo to give 20 g of red oil. The crude product was purified on silica using a stepwise gradient of 10% to 20% ethyl acetate: hexane to afford Spiro[cyclopropane-1,3′-[3H]indol]-2′(1’H)-one (2.3 g, 11%).
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 59-48-3 is helpful to your research.
