分别以6-溴吡啶-2-甲酸和3-腈基-4-甲基-2,6-二氯吡啶为原料,经过酰胺化、肼取代、缩合等反应合成4种新型吡啶腙类Schiff碱有机配体:N-苯基-2-甲酰胺-6-肼吡啶缩水杨醛;N-苯基-2-甲酰胺-6-肼吡啶缩香草醛;N-苯基-2-甲酰胺-6-肼吡啶缩对羟基苯甲醛;3-腈基-4-甲基-2,6-二肼吡啶二缩水杨醛。通过红外光谱、核磁共振谱对其结构进行了表征。
Four novel pyridine hydrazone Schiff bases were synthesized by 6-bromopyridine-2-carboxylic acid and 3-nitrile-4-methyl-2,6-dichloropyridine respectively through amidation, hydrazine substitution and condensation reaction Organic ligands: N-phenyl-2-formamido-6-hydrazinopyridine salicylaldehyde; N-phenyl-2-carboxamide-6-hydrazinopyridine; vanillin; N-phenyl- Hydrazinopyridine-p-hydroxybenzaldehyde; 3-nitrile-4-methyl-2,6-dihydrazinopyridine disaluminal. Its structure was characterized by infrared spectrum and nuclear magnetic resonance spectrum.
