3,5-Disubstituted 3H-1,2,4-dithiazoles were prepared by the oxidation of dithiobiurets, S-benzylisodithiobiurets, and alkyl trithioallophanates, and then 3-acyl or carbamoylimino derivatives were obtained by the direct acylation or carbamoylation of the dithiazole salts. From the spectral data of these compounds, it is concluded that the carbonyl group affects the pseudoaromatic character of the dithiazole
通过二硫代缩二脲、S-苄基异二硫代缩二脲和三硫代脲基甲酸烷基酯的氧化制备3,5-二取代的3H-1,2,4-二噻唑,然后将二噻唑盐直接酰化或氨基甲酰化得到3-酰基或氨基甲酰亚氨基衍生物. 从这些化合物的光谱数据可以得出结论,羰基影响了二噻唑环系统的假芳族特征。
