Electric Literature of 51760-21-5, The chemical industry reduces the impact on the environment during synthesis 51760-21-5, name is Dimethyl 5-bromoisophthalate, I believe this compound will play a more active role in future production and life.
C (3.3 g, 0.012 mol), bis(pinacolato)diboron (3.4 g, 0.013 mol), dried potassium acetate (3.6 g), [l,r-Bis(diphenylphosphino)ferrocene]palladium(II) dichloride (Pd(dppf)Cl2, 0.2 g, 0.27 mol) were mixed in a 250 mL flask and evacuated for 1 hour before 100 mL dried, degassed l,4-dioxane was added. The reaction was stirred at 80 C under nitrogen atmosphere for 24 hours. After the reaction was completed, organic solvent was removed by rotovap and the remained solid was extracted with dichloromethane. The crude product was purified through a silica plug with a eluent of petroleum ether: ethyl acetate= 8: 1 to give pure D as a white solid (3.5 g, 90 % yield).
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, Dimethyl 5-bromoisophthalate, other downstream synthetic routes, hurry up and to see.
