Hypervalent Iodine Reagent Mediated Reaction of [60]Fullerene with Amines
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.
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.
