19932-85-5, 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. 6-Bromobenzo[d]oxazol-2(3H)-one, cas is 19932-85-5,the benzoxazole compound, it is a common compound, a new synthetic route is introduced below.
[0156j Triethylamine (0.72 g, 1.0 mL, 7.1 mmol) was added to a stirring a mixture of 6- bromo-2benzoxazilinone (0.89 g, 4.2 mmol) and trityichioride (1.21 g, 4.4 mmol) in CH2C12 (10 mL) for a period of 10 mm. The reaction was monitored by TLC (silica gel) and concentrated after 1 h. The concentrate was diluted with water and sonicated to form a heterogeneous solution. The resulting off-white solid was suction filtered and dried to provide 1 -trityl-6-bromo-2- benzoxazilinone (2.0 g). LCMS: rt 9.45 mm (A), purity 96 %, MS (mle) 456 (MHj.
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 6-Bromobenzo[d]oxazol-2(3H)-one, 19932-85-5
