In connection with our work on styryl derivatives of benzodiazinones, we have prepared the 7-N,N-dimethylamino-3-methyl-1,4-benzodiazin-2-one 4a and two chromo- and fluoroionophores derived from the monoaza-15-crown-5 and styrylbenzodiazinones. A structural study of these compounds by 1H and 13C NMR, UV spectrophotometry, and molecular modelling was carried out. Unlike styrylbenzoxazinones, styrylbenzodiazinone
结合我们对苯并二嗪酮的苯乙烯基衍生物的研究,我们制备了 7-N,N-二甲氨基-3-甲基-1,4-苯并二嗪-2-one 4a 和两种衍生自单氮杂-15-的发色和氟离子载体冠 5 和苯乙烯基苯并二嗪酮。通过 1H 和 13C NMR、紫外分光光度法和分子模型对这些化合物进行了结构研究。与苯乙烯基苯并恶嗪酮不同,苯乙烯基苯并二嗪酮衍生物在乙腈溶液中显示出 Z/E 异构化。异构化是光诱导的,由金属离子催化,是一个可逆的过程。此外,还描述了苯并二嗪酮的内酰胺官能团的有效烷基化反应。
