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.
General procedure: Intermediates 10-17 were prepared following literature methods [49] with slight modifications. 2-Benzoxazolone 8 or 2-benzothiazolone 9 (7.4mmol), appropriate 1-omega-dibromoalkane (8mmol), potassium carbonate (8mmol) and acetone (10mL) were refluxed for 4h and then allowed to stand at room temperature. The mixture was filtered to eliminate inorganic material and then evaporated under reduced pressure to obtain a residue, which was taken up in water. The solution was extracted with dichloromethane (3×50 mL) and the combined extracts were washed with water, dried, and evaporated. The residue was triturated twice with light petroleum ether 40-60C to give intermediates 10-17 that were used without further purification in the subsequent steps. Analytical and spectral data are reported only for unknown compounds 13 and 17.
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
