摘要
合成了两个希夫碱9 H -咔唑-3-碳醛-4-苯基硫代氨基脲酮(CCPTSC)和2-噻吩碳醛-4-甲基硫代氨基脲酮(tccmtsc)。采用元素分析、摩尔电导率、傅里叶变换红外光谱(FT-IR)、核磁共振光谱(NMR)和x射线粉末衍射(XRD)对CCPTSC和tccmtsc进行了表征。所有的光谱研究都证实了CCPTSC和tccmtsc的形成。基于热重分析(TGA)研究报道了这两种希夫碱的热稳定性。本文介绍了9 H -咔唑-3-碳醛-4-苯基硫代氨基脲酮(CCPTSC)和2-噻吩-碳醛-4-甲基硫代氨基脲酮(tccmtsc)两种新配体的合成和表征。采用元素分析、傅里叶红外光谱(FT-IR)、核磁共振光谱(NMR)、x射线粉末衍射(XRD)等手段对新合成的螯合剂进行了表征。用热重分析方法确定了这些化合物的热稳定性。
Synthesis and Characterization of 9H-Carbazole-3-carbaldehyde-4-phenylthiosemicarbazone and 2-Thiophenecarboxaldehyde-4-methyl-thiosemicarbazone
: Two Schiff bases 9 H -carbazole-3-carbaldehyde-4-phenylthiosemicarbazone (CCPTSC) and 2-thiophenecarboxaldehyde-4-methylthiosemicarbazone (TCMTSC) were synthesized. Both the CCPTSC and TCMTSC were characterized by elemental analysis, molar conductivity studies, Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance spectroscopy (NMR), and x-ray powder diffraction (XRD). All the spectral studies confirmed that the formation of both CCPTSC and TCMTSC. Thermal stabilities of the both Schiff bases were reported based on thermogravimetric analysis (TGA) studies. This paper describes synthesis and characterization of two new ligands namely, 9 H -carbazole-3-carbaldehyde-4-phenylthiosemicarbazone (CCPTSC) and 2-thiophene-carboxaldehyde-4-methylthiosemicarbazone (TCMTSC). These newly synthesized chelating agents were characterized with elemental analysis, Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance spectroscopy (NMR), x-ray powder diffraction (XRD). The thermal stabilities of these compounds were established with thermogravimetric analysis studies.
