Efficient Acetalization of Epoxy Rings on a Fullerene Cage

Efficient Acetalization of Epoxy Rings on a Fullerene Cage

Fullerene epoxides react with benzaldehyde derivatives in the presence of a pyridinium hexafluoroantimonate to give corresponding 1,3-dioxolane derivatives of [60]fullerene in excellent yields. The activation energy for the reaction of fullerene monoepoxide with benzaldehyde was determined to be 112...

description Fullerene epoxides react with benzaldehyde derivatives in the presence of a pyridinium hexafluoroantimonate to give corresponding 1,3-dioxolane derivatives of [60]fullerene in excellent yields. The activation energy for the reaction of fullerene monoepoxide with benzaldehyde was determined to be 112.7 kJ mol−1. This result shows that fullerene epoxides undergo the stepwise SN1-like acetalization reaction.
