制备方法与用途

应用

2-氯-1,3-二溴苯是一种有机中间体，可以通过重氮化反应从2,6-二溴苯胺制备得到。这种化合物可用于制备电致发光材料。

制备

在65℃下，向含有亚硝酸异戊酯（585mg，5mmol）和CuCl（396mg，4mmol）的10mL乙腈溶液中缓慢加入2,6-二溴苯胺（502mg，2mmol）。反应混合物在相同温度下搅拌2小时后，逐滴加入NH4BF4溶液（4.2g，40mmol）。随后，在0-10℃下继续搅拌1小时，并冷却至室温。接着，进行减压浓缩，用乙酸乙酯（30mL）溶解，用水（20mL）洗涤有机层。将有机层经无水硫酸钠干燥后过滤并再次减压浓缩。通过柱色谱法纯化残余物，使用石油醚洗脱，最终得到固体的2-氯-1,3-二溴苯（产率49%）。
