Synthetic Route of 1295502-53-2, The chemical industry reduces the impact on the environment during synthesis 1295502-53-2, name is 4,7-Dibromo-5,6-difluorobenzo[c][1,2,5]thiadiazole, I believe this compound will play a more active role in future production and life.
(1) Formula (IIb) the compounds of formula [brief records compound (IIb), the cartridge] (3.68 g, 11 . 60 mmol) dissolved in 200 ml anhydrous alcohol, under stirring at room temperature slowly adding NaBH4(4.52 G, 116.0 mmol), room temperature reaction 6 h. Adding water steaming and remove the anhydrous ethanol (100 ml) and methylene chloride (100 ml), the standing liquid, organic phase dried with anhydrous sodium sulfate, rotary evaporated to remove the dichloromethane to obtain white solid [compound IIIc] 2.84 g, yield 81.0%.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4,7-Dibromo-5,6-difluorobenzo[c][1,2,5]thiadiazole, other downstream synthetic routes, hurry up and to see.
