Application of 117635-21-9, The chemical industry reduces the impact on the environment during synthesis 117635-21-9, name is 1,4-Dibromo-2,5-dihexylbenzene, I believe this compound will play a more active role in future production and life.
[N-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-[1,1′-biphenyl]-4-amine](15) (1.2g, 3.3mmol)And 1,4-dibromo-2,5-dihexylbenzene] (16) (0.6 g, 1.5 mmol)To this reaction flask is added toluene / EtOH / 2N K2CO3 (aq) (2v: 1v: 1v) solvent.Degassing using a vacuum pump. Pd (PPh3) 4 (347 mg, 0.3 mmol) was added to the reaction flask and stirred at 90 for one day. Ethanol was removed using a vacuum evaporator and organic matter was extracted with dichloromethane (DCM). The organic layer was dried over MgSO4, filtered and purified by column to obtain 730 mg (yield 66%) of Intermediate 17
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, 1,4-Dibromo-2,5-dihexylbenzene, other downstream synthetic routes, hurry up and to see.
