摘要
The discovery of a rearrangement reaction of 5-amino-1-arylaminocarbonyl-1,2,triazole(pyrszole)to 5-arylureylene-1,2,4-trazole and the mechanism for thisrearrangement reaction are presented. The rearrangement reaction could be attributed to athermodynamic energy preference leading to the predominant formation of 5-aryluretjlene1,2,4-triazole,as shown by molecular mechanics calculation with MMX Program.
