Perkin communications. 4-(1,2,4-Triazolyl) cation: possible generation and reactions
Abstract
Thermolysis of N-(1,2,4-triazol-4-yl)-2,4,6-trimethylpyridinium tetrafluoroborate 3 in mesitylene–hexafluoroisopropyl solution gives a variety of products, but none derived from attack of the free nitrenium ion upon mesitylene; a possible explanation is a SET from trimethylpyridine to the nitrenium ion within the solvent cage.
