Reactions of [60]fullerene with alkynes promoted by OH-

In the current work, the reactions of [60]fullerene with alkynes promoted by OH- (base) are addressed. The treatment of C-60 with alkynes in the presence of TBAOH produces alkynylation products (R-C-60-H) with high selectivity in o-DCB at 100 degrees C. Plausible reaction mechanisms were proposed. This work provides a convenient and environmental friendly method for the functionalization of fullerenes.
