where distant sulphonyl groups are present, is very variable. There is some correlation between reactivity of the vinyl group and its π-ionisation potential which is high in the present molecules relative to comparison olefins. This increase is thought to be due to the presence of orbital interactions through bonds and/or through space between the sulphone group and the double bond, making the latter electron
由存在远的磺酰基的一系列双环烯烃形成氮丙啶和/或环氧化物的难易程度是非常可变的。乙烯基的反应性与其π-电离电势之间存在一些相关性,相对于比较烯烃,其在本发明分子中较高。认为这种增加是由于通过键和/或通过砜基团和双键之间的空间存在轨道相互作用,从而使后者的电子不足。通过UV-光电子能谱确定电离电势,并通过采用从头算构型相互作用方法进行分配。
