摘要:
The hypervalent iodine reagent mediated reaction of C-60 with various readily available amines for the easy preparation of iminofullerenes has been developed. The reaction between C-60 and sulfonamides can be effectively controlled to selectively synthesize azafulleroids or aziridinofullerenes under PhI(OAc)(2)/I-2 or PhIO/I-2/CuCl/lutidine conditions, respectively. For phosphamide and urea, only one isomer is obtained. However, carbamate gives three kinds of products. Interestingly, the reaction of C-60 with alkylamines allows the effective synthesis of aziridinofullerenes and regioselective cis-1-bisaziridinofullerenes.
