在本篇論文中,我們對釕金屬催化炔與疊氮化合物經環化加成反
應形成1,2,3-三氮唑做探討。由異構化的實驗當中,我們發現1,2,3-三氮唑結構穩定。也利用Hammett 方程式與動力學的實驗,發現在苯環對位上接有推電子基的二苯乙炔較有利於產物的生成,且炔類的濃度會影響反應速率。
We have studied on the Ruthenium catalyzed cycloaddition of alkynes and azides to form 1,2,3-triazoles. In the isomerization studies, we found that the structure of 1,2,3-triazoles are stable. We have also found that
diarylacetylene bearing electron-withdrawing groups are more reactive than those with electron-donating groups, and the reaction rate is proportional to the concentration of alkynes.
