59-49-4, 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. 2-Benzoxazolinone, cas is 59-49-4,the benzoxazole compound, it is a common compound, a new synthetic route is introduced below.
EXAMPLE 251A 6-bromo-1,3-benzoxazol-2(3H)-one A mixture of 2-benzoxazolinone (3.00 g, 22.2 mmol), 1,3-dibromo-5,5-dimethylhydantoin (3.49 g, 12.2 mmol), and trifluoromethanesulfonic acid (5.00 g, 33.3 mmol) in dichloromethane (100 mL) at room temperature was protected from light, stirred for 1 hour, and concentrated. The concentrate was purified by flash column chromatography on silica gel with 50% ethyl acetate/hexanes to provide the desired product.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 2-Benzoxazolinone, 59-49-4
