报道了5-甲基-3-亚甲基哌啶水杨醛及5-溴-3-亚甲基哌啶水杨醛和5-溴-3-亚甲基吗啡林水杨醛的合成;同时报道了含二级胺桥联的Salen-类Schiff碱及其还原产物的合成。初步研究分析了双位配体Schiff碱的金属盐配合物的稳定性及其水解产物。并通过核磁共振、红外、质谱等手段对相关化合物结构进行了表征。
The synthesis of 5-methyl-3-methylenepiperidine salicylaldehyde and 5-bromo-3-methylenepiperidine salicylaldehyde and 5-bromo-3-methylenemorphine salicylaldehyde was reported. The synthesis of Salen-type Schiff bases containing secondary amine bridges and their reduction products was also reported. The preliminary study analyzed the stability of the metal salt complex of the double ligand Schiff base and its hydrolyzate. The structures of related compounds were characterized by means of nuclear magnetic resonance, infrared and mass spectrometry.
