1122-10-7, 3,4-Dibromo-1H-pyrrole-2,5-dione is a pyrrolines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
1122-10-7, In a 50 mL two-necked flask,A mixture of NaH (30 mg, 0.75 mmol, 60% by mass, dispersed in paraffin) was suspended in 5 mL of DMF, and 5 mL of DMF dissolved in 2,3-dibromomaleimide (127.5 mg, 0.5Mmol) and low temperature reaction for 30 min,(47muL, 0.75mmol), low temperature reaction 30min, dropping saturated NH4Cl solution to terminate the reaction, CH2Cl2 extraction, organic layer evaporated, silica gel column chromatography,Petroleum ether: ethyl acetate = 30: 1 (v / v) to give 92 mg of white crystals (82a) in 69% yield.
As the paragraph descriping shows that 1122-10-7 is playing an increasingly important role.
