3-R-1,2,4-Triazol-5-ones are adamantylated in sulfuric acid. The reaction involves the N1 atom of the ring. 4-Adamantyl-1-methyl-, 1-adamantyl-4-methyl-, and 1,4-diadamantyl-1,2,4-triazol-5-ones were also prepared. Therewith, it was found that N1 exhibits a higher reactivity than N4.
3-R-1,2,4-三唑-5-酮在硫酸中发生金刚烷化反应。反应涉及环的 N1 原子。还制备了 4-金刚烷基-1-甲基、1-金刚烷基-4-甲基和 1,4-二金刚烷基-1,2,4-三唑-5-酮。结果发现,N1 的反应活性高于 N4。
