presence of triethylamine afforded the corresponding 1,3,4-thiadiazole derivatives 10, 11, 13, 14 and 22–29. Stirring of N,2-diaryldiazene-1-carbohydrazonoyl chlorides 1–3 with thioanilides 31A–E in acetonitrile at room temperature in the presence of triethylamine gave the corresponding 1,3,4-thiadiazol-2(3H)-ylidene derivatives 34–36. The structures of all new compounds 10, 11, 13, 14, 22–29 and 34–36
摘要 的反应Ñ,2- diaryldiazene -1- carbohydrazonoyl氯化物1,2与2 - ((甲硫基)-carbonthioyl)腙7,12和18-21的无水乙醇在三乙胺,得到存在室温下相应的1,3- ,4-噻二唑衍生物10,11,13,14和22-29。在室温下,在三乙胺存在下,在乙腈中用硫代苯胺31A-E搅拌N,2-二芳基二氮杂-1-碳酰重氮酰氯1-3,得到相应的1,3,4-噻二唑-2(3 H)-亚烷基衍生物34 –36。所有新化合物的结构通过元素分析和光谱数据确定了10、11、13、14、22-29和34-36。研究了一些针对金黄色葡萄球菌和大肠杆菌的新合成化合物,最有效的化合物是3-苯基-5-(苯基二氮烯基)-2-((1-(吡啶-2-基)亚乙基)hydr基)-2,3-二氢-1,3,4-噻二唑(13c),2-((1-(吡啶-2-基)亚乙基)肼基)-3-(对甲苯基)-5-(对甲苯二重氮基)-2
