Homolytic substitution of monosubstituted benzenes by 1-adamantyl radical has been carried out and the reactivity and the polar character of the radical have been determined by examining the effects of substituents on isomer distributions and on relative reactivities. The results indicated that the 1-adamantyl radical has nucleophilic properties which are more pronounced than that of other more strained
已经通过1-金刚烷基进行了单取代苯的均质取代,并且通过检查取代基对异构体分布和相对反应性的影响,确定了该基团的反应性和极性特征。结果表明,1-金刚烷基具有亲核性质,比其他应变更大的桥头基更明显。建议将这种行为归因于在将桥头基团添加到芳族底物中的过程中极性效应所起的不同作用。还描述了几种单取代的1-芳基金刚烷的合成。
