Selective Functionalization of Fullerenes with<i>N</i>,<i>N</i>-Dihalosulfonamides as an N<sub>1</sub>Unit: Versatile Syntheses of Aza[60]fulleroids and Aziridino[60]fullerenes and their Application to Photovoltaic Cells
Highly selective and versatile methods for the synthesis of aza[60]fulleroids and aziridino[60]fullerenes from C60 have been developed. The reactions utilized N,N‐dihalosulfonamides as an N1 source. The photophysical, electrochemical, and thermal properties of the iminofullerenes were investigated by means of UV/Vis spectroscopy, cyclic voltammetry, and thermogravimetry, respectively. Furthermore,

The BF3·Et2O-catalyzed formal [3 + 2] reaction of aziridinofullerenes with various carbonylcompounds for the easy preparation of fullerooxazolidines has been developed. Moreover, the reaction of aziridinofullerene with ethyl formate affords the simplest fullerooxazole without substituent.

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.
