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. 1996-29-8, name is 1-Bromo-4-chloro-2-fluorobenzene belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. HPLC of Formula: C6H3BrClF
1-Bromo-4-chloro-2-fluorobenzene (61g, 291mmol), 2,6-dimethoxyphenylboronic Acid (50.4g, 277mmol), K2CO3 (60.4g, 437mmol) and Pd(PPh3)4 (10.1g, 8.7mmol) were added to a round bottom flask and dissolved in THF (500ml) and distilled water (200ml) and stirred under reflux at 60 C for 12 hours. After completion of the reaction, remove the water layer and perform column chromatography (Hexane: DCM (20%)), by using the intermediate (Int-1) to afford 38g (51%)
The synthetic route of 1996-29-8 has been constantly updated, and we look forward to future research findings.
