Relative rates of the photoreactions of 1-(1), 2-(2) and 4(5)-valerylimidazole (3) as well as the yields of photo-fragmentation product 10 from 1-(7), 2-(8) and 4(5)-stearoylimidazole (9), respectively, were determined. A reaction path via Norrish Type II fragmentation involving the carbonyl group of 1-acylimidazoles was ruled out.
1-(1),2-(2)和4(5)-缬草咪唑(3)的光反应的相对速率以及1-(7),2-(8)的光裂解产物10的产率分别测定了4和(5)-硬脂基咪唑(9)。排除了通过Norrish II型断裂反应涉及1-酰基咪唑的羰基的反应路径。
