Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 611-09-6, name is 5-Nitroindoline-2,3-dione, A new synthetic method of this compound is introduced below., Safety of 5-Nitroindoline-2,3-dione
General procedure: A mixture of an isatin (1mmol), molononitrile (1mmol), CH activatedacid (1mmol), and [C4(DABCO)2]¡¤2OH(2mol%) inwater (3mL)was stirred at 80 C. The reaction progress was monitored by TLC [eluent:n-hexane:EtOAc (9:2)] (It is important to that by beginning of thereaction the products were precipitated in the reaction medium).After completion of the reaction, the mixture was cooled to room temperature and the solid product was filtered, washed with cold distilledwater (2 mL) to obtain essentially pure products. The solid productswere recrystallized from ethanol if necessary.
The synthetic route of 611-09-6 has been constantly updated, and we look forward to future research findings.
