132244-31-6, 5-Bromobenzo[d]oxazole is a benzoxazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: An oven-dried 10 mL reaction vial equipped with a stir bar was charged with azole heterocycles (1, 0.2 mmol, 1.0 equiv) and alkenyl bromides (2, 0.30 mmol, 1.5 equiv) in a glove box under a nitrogen atmosphere. A solution of catalytic Pd2(dba)3 (9.15 mg, 0.01 mmol, 5 mol%) and NiXantphos (11.03 mg, 0.02 mmol, 10 mol%) was stirred in 1 mL of dry tetrahydrofuran (THF) for 2 h at room temperature. Then, t-BuONa (57.7 mg, 0.6 mmol, 3.0 equiv) and reagent mixed with catalyst were added to the reaction mixture. And thenthe vial was capped. According to the temperature requirements for different products, some vials were stirred in the glove box for 24 h, but others were removed from the glove box, and stirred for 24 h at 70 or 150 . The reaction mixture was quenched with three drops of H2O, diluted with 3 mL of ethyl acetate, and filtered over a pad of silica. The pad was rinsed with ethyl acetate (15-25 mL), and the combined solutions were concentrated in vacuo. The crude material was loaded onto a deactivated silica gel column and purified by flash chromatography to afford the desired product.
As the paragraph descriping shows that 132244-31-6 is playing an increasingly important role.
