Reference of 1677-48-1, 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. 1677-48-1, name is 5,6-Dichloroindoline-2,3-dione belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
1.08 g of 4,5-dichloroindoloquinone and 1.08 g of 5,6-dichloroindole quinone were weighed into a 100 ml three-necked flask, 40 ml of dichloromethane, 0.38 g of sodium borohydride The reaction temperature: 40 , after the end of the reaction, the rotary evaporation to remove the solvent, the crystal to be purple solid 5,6,4 ‘, 5’-tetrachloroindiu red crude 1.03, the reaction time: 4.0h, reaction temperature: 40 , G, yield 51.5%.
The synthetic route of 5,6-Dichloroindoline-2,3-dione has been constantly updated, and we look forward to future research findings.
