1423-61-6, 7-Bromobenzo[b]thiophene is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Dichloro l,l ‘-bis(diphenylphosphino)ferrocene palladium(II) (14 g, 0.018 mol) was added to a mixture of 7-bromo-l-benzothiophene (Intermediate XI 3) (75 g, 0.35 mol, from Step 2), bis(pinacolato)diboron (110 g, 0.42 mol), potassium acetate (170 g, 1.8 mol), and toluene (750 mL) at room temperature under an argon atmosphere. The reaction mixture was then heated at 100 C. After 12 h, the reaction mixture was cooled to room temperature, partitioned between water and ethyl acetate, and the layers were separated. The organic material was washed sequentially with water and brine, dried (sodium sulfate), filtered, and the filtrate was concentrated under a vacuum. The residue was subjected to flash chromatography on silica gel (99: 1 hexane-ethyl acetate) to give 2-(l-benzothiophen-7-yl)-4,4,5,5-tetramethyl-l,3,2-dioxaborolane (60 g, Intermediate Y2) as a colorless solid, 1423-61-6
As the paragraph descriping shows that 1423-61-6 is playing an increasingly important role.
