Related Products of 26670-89-3,Some common heterocyclic compound, 26670-89-3, name is 2-Bromo-4-iodo-1-methylbenzene, molecular formula is C7H6BrI, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
(2-2) Synthesis of 2-Bromo-1-Methyl-4-Phenylbenzene (0144) A mixture of 2-bromo-4-iodotoluene (14.5 g) obtained by the step (2-1), phenylboronic acid (6.35 g), tetrakis(triphenylphosphine)palladium (0) (1.69 g), potassium carbonate (20.2 g), 1,4-dioxane (117 mL), and water (13 mL) was refluxed for 3 hours in an argon atmosphere. The resulting reaction mixture was returned to room temperature, and extracted with dichloromethane. The organic layer was washed with a saturated sodium chloride solution, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to obtain 2-bromo-1-methyl-4-phenylbenzene (8.6 g). The yield was 71%.
The synthetic route of 26670-89-3 has been constantly updated, and we look forward to future research findings.
