4923-87-9, 5-Bromobenzothiophene is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: Under an argon atmosphere, Pd(OAc)2 (3.3 mg, 0.015 mmol, 5 mol%),ligand [1,1?-biphenyl]-2-yldiphenylphosphane (15 mg, 0.045 mmol,15 mol%), HCO2NH4 (23 mg, 0.36 mmol), MeCO2NH4 (35 mg, 0.45mmol), benzopheneone N-tosylhydrazone 5a (126 mg, 0.36 mmol),and Cs2CO3 (195 mg, 0.6 mmol) were successively added to a flamedried flamedried25 mL Schlenk flask. The reaction flask was degassed threetimes with argon and anhyd tert-pentyl alcohol (3.0 mL) was addedusing a syringe. Then 1-bromo-4-(tert-butyl)benzene (2b; 64 mg, 0.3mmol) was added with a syringe. Note that the aryl bromide in a solidform was added to the reaction flask prior to Cs2CO3. The reactionwas heated at 90 C with stirring for about 4 h, then it was cooled tor.t., and filtered through a short pad of neutral alumina with EtOAc(25 mL) as eluent. Solvent was then removed in vacuo to leave a crudemixture, which was purified by silica gel column chromatography(eluent: PE); yellow solid (82 mg, 91%).
4923-87-9, As the paragraph descriping shows that 4923-87-9 is playing an increasingly important role.
