制备方法与用途

简介

2-氯-5-硝基苯磺酰氯是芳香烃衍生物的一种。由于其官能团含有硝基、卤素以及磺酰氯，因此可以很容易与其他化合物发生反应，使其成为制备精细化学品和原料药的重要有机中间体。

制备

在250毫升三口瓶中加入100毫升盐酸和10克2-氯-5-硝基苯胺，搅拌溶解后降温至约0℃。随后，缓慢滴加6.0克亚硝酸钠溶于50毫升水中制得的溶液，滴加完毕后保温并搅拌1小时。

接着将上述获得的重氮离子溶液缓慢加入预先用二氧化硫气体饱和的5克二水合氯化铜溶解在500毫升乙酸中的冰浴冷却混合物中。同样地，在0℃下保温并搅拌反应混合物1小时后，再在剧烈搅拌下将其分批加入到冰水中。过滤收集分离出的固体，并用清水洗淋，然后在真空条件下干燥，最终得到所需产物——37，呈奶油色粉末（产率55%，质量8.2克）。

用途

作为医药及染料中间体使用。
