nonconjugated 4,4′-methylenediphenyl linkers was developed. The reaction of azomethine ylides derived from the bisaziridines with fullerene C60 was optimized and used for the stereoselective preparation of both the monoadducts (C60–linker–aziridine dicarboxylate), and the dumbbell bisadducts (C60–linker–C60). The reasons for the observed selectivity of the azomethine ylide formation and cycloaddition
开发了具有通过共轭对亚苯基,部分共轭的1,1'-联苯-4,4'-二基和非共轭4,4'-亚甲基二苯基连接体连接的两个氮丙啶单元的烷氧羰基取代的双氮丙啶的合成。甲亚胺叶立德的反应从与富勒烯C的bisaziridines衍生60进行了优化,并同时用于单加成物(C的立体选择性制备60 -接头-氮丙啶二羧酸酯),和哑铃bisadducts(C 60 -接头-C 60)。从理论上研究了在DFT B3LYP / 6-31G(d)或ONIOM B3LYP / 6-31G(d):B3LYP / STO-3G对富勒烯-的反应中观察到的甲亚胺叶立德形成和环加成选择性的原因。含有分子。
