Reactions of 4,6-dibromo-2,1,3-benzoxadiazole with phenols or arenelthiols lead to 4-aryloxy-6-bromo-2,1,3-benzoxadiazoles or 4-arylthio-6-bromo-2,1,3-benzoxadiazoles, respectively. Isomeric 6-aryloxy-4-bromo-2,1,3-benzoxadiazoles were synthesized by replacement of the fluorine atom in 2,6-dibromo-4-fluoro-1-nitrosobenzene with phenols and treatment of the resulting 4-aryloxy-2,6-dibromo-1-nitrosobenzene with sodium azide.
4,6-二溴-2,1,3-苯并恶二唑与酚或芳基硫醇反应,分别生成4-芳氧基-6-溴-2,1,3-苯并恶二唑或4-芳硫基-6-溴-2,1,3-苯并恶二唑。通过用酚替换2,6-二溴-4-氟-1-硝基苯中的氟原子并处理所得的4-芳氧基-2,6-二溴-1-硝基苯与叠氮化钠,合成了异构的6-芳氧基-4-溴-2,1,3-苯并恶二唑。
