摘要

Abstract 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.
