-
摘要:以水杨醛、对硝基(氯、甲氧基)苯胺、乙二胺、二乙烯基三胺为原料,经过先偶联后桥连的方法,合成了 2类双偶氮生色开链冠醚,其结构特征是氮杂链作桥链,酚羟基作端基,对位取代的苯偶氮基作为生色基团,形 成新的双偶氮化合物5和6的结构经元素分析,红外光谱和质谱得到确定.Abstract:Two new types of bis-azo chromogenic acyclic crown ethers with brigded chains of azachains and terminals of phenolic hydroxyl and chromogens of 4-R benzenediazo groups 5 and 6 have been conveniently synthesized with good yields via coupling-bridging reactions from salicyladehyde, 4-nitro (-chloro,-methoxy) benzeneamine, ethyldiamine and diethylenetriamine, respectively.Their structures of them have been confirmed by MS,IR measurement and elemental analyses.
