95-15-8, Thianaphthene is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
95-15-8, General procedure: To a stirred, cooled (0 C) solution of 2,2,6,6-tetramethylpiperidine (0.25 mL, 1.5 mmol) in THF (2-3 mL) were successively added BuLi (about 1.6 M hexanes solution, 1.5 mmol) and, 5 min later, ZnCl2?TMEDA14 (0.13 g, 0.50 mmol). The mixture was stirred for 15 min at 0 C before introduction of the substrate (1.0 mmol) at 0-10 C. After 2 h at room temperature, a solution of I2 (0.38 g,1.5 mmol) in THF (4 mL) was added. The mixture was stirred overnight before addition of an aqueous saturated solution of Na2S2O3(4 mL) and extraction with AcOEt (3 20 mL). The combined organic layers were dried over MgSO4, filtered and concentrated under reduced pressure. To the crude iodide were added Cs2CO3(0.65 g, 2.0 mmol), Cu powder (13 mg, 0.20 mmol), the azole (1.5 mmol) and MeCN (5 mL) and the resulting mixture was heated under reflux for 24 h. Filtration over Celite, washing with AcOEt,removal of the solvent and purification by chromatography on silica gel (the eluent is given in the product description) led to the compound described below.
95-15-8 Thianaphthene 7221, abenzothiophene compound, is more and more widely used in various fields.
