The intramolecular cyclization of 1- acylbithiourea 1 gave 1,2,4-triazole 2 and 1,3,4-thiadiazole 3. The reaction of 1 with p-toluenesulfonyl chloride in the presence of trithylamine afforded 3. Treatment of 1 with methyl iodide in the absence of any base yielded 2-methylthio-1,3,4-thiadiazole 10 and 2-imino- 1,3,4-thiadiazoline 12.
1-酰基联硫脲1的分子内环化得到1,2,4-三唑2和1,3,4-噻二唑3。的反应1与p甲苯磺酰氯在trithylamine的存在下,得到3。在没有任何碱的情况下用碘甲烷处理1得到2-甲硫基1,3,4-噻二唑10和2-亚氨基-1,3,4-噻二唑啉12。
