• 定義

  ChEBI: 2-benzoxazolinone is a member of the class of benzoxazoles that is 2,3-dihydro-1,3-benzoxazole carrying an oxo group at position 2. It has a role as an allelochemical and a phytoalexin.

• 製造方法

  2-benzoxazolinone synthesis method: add o-aminophenol, urea and solvent chlorobenzene into the reaction kettle, protect with nitrogen, the reaction temperature is 50～132 ℃, the reaction time is 6h, after the reaction is completed, it is cooled with ice brine, crystallized, Filter the finished product. It is also possible to use o-aminophenol to react with phosgene in the solvent chlorobenzene, quickly pass phosgene within 20 ~ 40 ° C, then heat up to 100 ~ 130 ° C, and then pass phosgene at a lower speed, after the reaction is completed, pass nitrogen to catch up. Phosgene, after work-up, can also obtain 2-benzoxazolinone.

• 一般的な説明
