An Alternative Type of Fullerene Products from the Reaction of [60]Fullerene with Alkoxides and Subsequent Derivatization
摘要:
Reaction of [60]fullerene with freshly prepared RCH(2)CH(2)ONa/RCH(2)CH(2)OH (R = H, Me, Et, Ph) in anhydrous toluene in the presence of air unexpectedly afforded fullerene products with a C(60)-fused tetrahydrofuran ring Skeleton and an acetal moiety, which could be further transformed into C(60)-fused dihydrofurans, tolyl-substituted C(60)-fused tetrahydrofuran, and methanofullerenes bearing a formyl group by boron trifluoride etherate. Possible reaction mechanisms are proposed to explain the formation of different fullerene products.

CuI-catalyzed reaction of C60 with tertiaryamines by using air as the sole oxidant has been developed. Spiro-linked methanofullerenes bearing cyclic amides and fullerenoalkanals can be obtained selectively using the cyclic and acyclic amines as starting materials, respectively. The reactions show a wide functional group tolerance. In addition, four ([6,6]-phenyl-C61-butyric acid methyl ester) analogues
