In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 324-03-8, name is 6-Fluoroindoline-2,3-dione belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below. SDS of cas: 324-03-8
General procedure: A 25-mL flask, equipped with a magnetic stirring bar, was charged with 2-(1,3-dithiolan-2- ylidene)acetonitrile 1a (143 mg, 1.0 mmol), isatin 2a (74 mg, 0.5 mmol), and MeCN (3.0 mL), followed by addition of a solution of I2 (25 mg, 0.1 mmol) in MeCN (1.0 mL). The reaction mixture was stirred at 80 C for 12 h. After 1a was consumed, as indicated by TLC, the reaction mixture was quenched with saturated aqueous Na2S2O3 (1.0 mL) and water (20.0 mL), and stirred for another 10 min. The fully precipitated solid was filtered and washed with water (20.0 mL). Then it was further washed with petroleum ether-ethyl acetate (1/1, V/V, 20.0 mL) and dried under vacuum to afford 3a.
The synthetic route of 324-03-8 has been constantly updated, and we look forward to future research findings.
