两种新含硫席夫碱的合成与表征

Synthesis and characterization of two new Schiff bases containing sulfur

报道了两种新含硫席夫碱──维生素Ｋ３单缩二氨基硫脲和丙酮酸二缩二氨基硫脲的合成。这两种化合物至今尚未见文献报道。通过元素分析、质谱、红外光谱和核磁共振氢谱对两种化合物的结构进行了表征。

This paper deals with the synthesis of two newSchiff bases containing sulfur-vitamin K3 monothiocarbohydrazone and pyruvic acid dithiocarbohydrazone. These two compounds have not yet beenreported in the literature so far. Their structures havebeen characterized by elemental analysis, MS, IR and1HNMR spectra.
