Name is 4-Bromoisothiazole, as a common heterocyclic compound, it belongs to isothiazole compound, and cas is 24340-77-0, its synthesis route is as follows.,24340-77-0
Step 1. 4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-isothiazole. To an oven dried schlenck flask charged with 6-bromo-isothiazole (0.5 g, 3.1 mmol), 4,4,5,5,4,4,5,5?-octamethyl-[2,2?]bi[[1,3,2]dioxaborolanyl] (0.85 g, 3.4 mmol), tri(dibenyzlideneacetone)dipalladium(0) (0.28 g, 0.31 mmol), tricyclohexylphosphine 20 (0.17 g, 0.61 mmol), potassium acetate (0.9 g, 9.14 mmol), followed by 1,4-dioxane (20 mL) was degassed for 5 min. under an atmosphere of nitrogen. The reaciton was heated at 100 C overnight, and cooled at rt. The reaction was diluted with dichloromethane, filtered through celite, washed with 1N sodium carbonate solution, water and brine, dried over sodium sulfate, and concentrated to give the product. LCMS m/z = 212 (M + 1).
With the complex challenges of chemical substances, we look forward to future research findings about 4-Bromoisothiazole
