We introduce 7-fluoro-4-N,N-dimethylaminosulfonyl-2,1,3-benzothiadiazole and 7-fluoro-4-N,N-dimethylaminosulfonyl-2,1,3-benzoselenadiazole as new fluorogenic reagents for amines. These reagents are nonfluorescent themselves and can easily react with nonfluorescent amines to produce environment-sensitive fluorophores. Herein, we report the synthesis of the new reagents and the fluorescence properties of the reagents and their amine derivatives as well as the reactivity of the new reagents toward amines.
我们介绍了 7-氟-4-N,N-二甲基氨基磺酰基-2,1,3-苯并噻二唑和 7-氟-4-N,N-二甲基氨基磺酰基-2,1,3-苯并硒二唑作为胺类的新型荧光试剂。这些试剂本身是无荧光的,但很容易与无荧光的胺发生反应,生成对环境敏感的荧光团。在此,我们报告了新试剂的合成、试剂及其胺衍生物的荧光特性以及新试剂对胺的反应性。
