The structures of the C4H7O+ and C3H6O+· dissociation products from selected C5H10O+· isomers with the oxygen on the first, second and third carbons were determined. The first product is CH3C(OH)CHCH2+ and the second is CH3C(OH+)CH2⋅ and CH3⋅CHCHOH+ in various proportions. These results demonstrate that ions with the oxygen on the first and third carbons isomerize partially to isomers with the oxygen on the second carbon. This and C5H10O+· isomers expected to be accessible to each other suggest that there are traversable pathways between about 60 C5H10O+· isomers, demonstrating how extensive interconversions of aliphatic radical cations can be.
确定了氧位于第一、第二和第三碳原子上的某些 C5H10O+- 异构体的 C4H7O+ 和 C3H6O+- 离解产物的结构。第一个产物是 CH3C(OH)CHCH2+,第二个产物是不同比例的 CH3C(OH+)CH2⋅和 CH3⋅CHCHOH+ 。这些结果表明,第一和第三碳上含氧的离子会部分异构为第二碳上含氧的异构体。这和 C5H10O+- 异构体预计可以相互转换的情况表明,在大约 60 种 C5H10O+- 异构体之间存在着可穿越的路径,这表明脂肪族自由基阳离子的相互转换是多么广泛。
