Synthetic Route of 19230-28-5, 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. 19230-28-5, name is 1,3-Dichloro-2-iodobenzene belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
In a 1-liter three-necked flask equipped with a thermometer and a condenser, 26 g of intermediate 12, 26.5 g of 1,3-dichloro-2-iodobenzene, 27 g of K2CO3, and 3 g of TBAB were sequentially added, and then 300 ml of toluene, 100 ml of ethanol, and 50 ml of water were added in this order. replace the air in the reaction bottle with nitrogen, add 0.56g Pd(PPH3)4 under nitrogen protection, turn on heating, magnetically stir, heat to (78-80 C) reflux reaction, sample and test after 6h, until the raw material reaction is complete The reaction was stopped, the temperature was lowered to room temperature for post-treatment, the reaction solution was filtered, and the layers were left to stand. The aqueous phase was extracted with 100 ml of toluene, and the organic phases were combined, washed with ultrapure water to neutrality, dried over anhydrous Na 2 SO 4 for 1 h, filtered to remove the desiccant, the filter cake was rinsed with a small amount of toluene, the filtrates were combined, and concentrated through a silica gel column to obtain intermediate 13. Intermediate 13 was 32 g of a white solid with a yield of 89%.
The synthetic route of 1,3-Dichloro-2-iodobenzene has been constantly updated, and we look forward to future research findings.
