Easy access to unprecedented mixed functionalized dihydrofullerenes C60RH and C60RR′: the C602− anion route
Abstract
Functionalized mixed dihydrofullerenes C60RH and C60RR′ are easily obtained from reactions between C602− anion and halo derivatives RX and R′X. The key step consists in the selective reaction of the intermediate [C60R]− ion, as soon as it is formed, with either CF3CO2H or R′X. This process is made possible thanks to the very fast single
