BF3·Et2O- or DMAP-Catalyzed Double Nucleophilic Substitution Reaction of Aziridinofullerenes with Sulfamides or Amidines
摘要:
BF3 center dot Et2O-catalyzed double nucleophilic substitution reaction of N-tosylaziridinofullerene with sulfamides has been exploited for the easy preparation of cyclic sulfamide-fused fullerene derivatives. Moreover, the Lewis base catalyzed double amination of N-tosylaziridinofullerene, with amidines as the diamine source, is demonstrated for the first time. The present methods provide new routes to cyclic 1,2-diaminated [60]fullerenes.

A FeCl3·6H2O-mediated reaction of [60]fullerene with amidoximes for the preparation of fulleroimidazolines has been presented. This reaction shows a wide substrate scope, and the products obtained from alkyl-substituted amidoximes are first disclosed. In addition, a possible mechanism is proposed.
CuI-Catalyzed Oxidative [3 + 2] Reaction of Fullerene with Amidines or Amides Using Air as the Oxidant: Preparation of Fulleroimidazole or Fullerooxazole Derivatives
CuI-catalyzed oxidative reaction of amidines with C60 using air as the oxidant has been exploited for the easy preparation of fulleroimidazole derivatives. Furthermore, this kind of CuI-catalyzed [3 + 2] reaction has also been successfully applied in the synthesis of fullerooxazole derivatives starting from amides for the first time. The substrate scope is broad, and the process is particularly cheap
