photostimulated reaction of the phthalimide anion (1) with 1-iodoadamantane (2) gave 3-(1-adamantyl) phthalimide (3) (12%) and 4-(1-adamantyl) phthalimide (4) (45%), together with the reduction product adamantane (AdH) (21%). The lack of reaction in the dark and inhibition of the photoinduced reaction by p-dinitrobenzene, 1,4-cyclohexadiene, and di-tert-butylnitroxide indicated that 1 reacts with 2 by an S(RN)1
邻苯二甲酰亚胺阴离子(1)与1-碘金刚烷(2)的光刺激反应得到3-(1-金刚烷基)邻苯二甲酰亚胺(3)(12%)和4-(1-金刚烷基)邻苯二甲酰亚胺(4)(45%),以及还原产物金刚烷(AdH)(21%)。在黑暗中缺乏反应,对二硝基苯,1,4-环己二烯和二叔丁基硝基氧的光诱导反应受到抑制,表明1通过S(RN)1机理与2反应。产物3和4的形成以二甲苯基阴离子为中间体。阴离子1与叔丁基氯化汞(10)的光诱导反应提供了独特的产物4-叔丁基邻苯二甲酰亚胺(11)。通过对1的竞争实验,发现1-iodoadamantane约为ca。反应活性是氯化叔丁基汞的10倍。
