芳杂环亚胺类N,N(O,S)-双齿配体合成与表征

利用廉价易得的2-呋喃甲醛、2-噻吩甲醛、2-吡啶甲醛等杂环芳甲醛以及正丁胺、苯胺等脂肪及芳香伯胺等为原料,在温和的实验条件下,合成了18种N, N(O, S)-亚胺类双齿配体。得到了优良的分离收率,最高达到了97%。产物为液体或固体化合物,分别测定了固体的熔点,并通过核磁共振谱(¹H NMR及¹³C NMR)及高分辨飞行时间质谱(HRMS)对所得产物的组成及结构进行了表征,表明其与目标化合物相符。

Synthesis and Characterization of N,N(O,S)-Bidentate Ligands for Aromatic Heterocyclic Imine

By using inexpensive and readily available hetero aromatic aldehyde, i.e. 2-furanaldehyde, 2-thiophene formaldehyde, 2-pyridine formaldehyde and aliphatic or aromatic primary amine, namely, n-butylamine, aniline and so on, eighteen N, N(O, S)-bidentate ligands of aromatic heterocyclic imine were synthesized by simple reaction under mild experimental conditions. Good isolated yields were obtained and up to the maximum of 97%. The products were liquid or solid, and the melting points of solid products were determined. All products were characterized through nuclear magnetic resonance spectrum (¹H NMR and ¹³C NMR) and high resolution time-of-flight mass spectrometry (HRMS). It was proved that the structures and components corresponded with target compounds.
