In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 4519-46-4, name is Methyl 2-bromoacrylate belongs to esters-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. SDS of cas: 4519-46-4
To a solution of methyl 2-bromo-2-propenoate (452 mg, 2.74 mmol) (for a synthesis see Rachon, J.; Goedken, V.; Walborsky, H. J. Org. Chem. (1989), 54(5), 1006) in degassed tetrahydrofuran (10 ml) under an argon atmosphere was added [2- (methyloxy)-8-quinolinyl]boronic acid (506 mg, 2.49 mmol), bis(tri-t- butylphosphine)palladium (0) (25 mg, 0.05 mmol), bis(dibenzylideneacetone)palladium(0) (23 mg, 0.025 mmol) and potassium fluoride (477 mg, 8.217 mmol). The reaction was heated at 7O0C for 24 hours and then treated with water and dichloromethane. The aqueous fraction was re-extracted with dichloromethane. The combined organic fractions were then dried (MgSO4) and the solvent removed under reduced pressure. The residue was subjected to chromatography on silica gel using a
The synthetic route of 4519-46-4 has been constantly updated, and we look forward to future research findings.
