A selective synthesis of the fullerene-fused dioxane adduct via heterogeneous reaction of C 60 with α-diols and NaOH under ultrasonication.

A novel ultrasonic-mediated approach to the synthesis of 1,9-dihydro[C60 -Ih ][5,6](1,4-dioxano)fullerene based on the heterogeneous reaction of fullerene with α-diols and NaOH has been developed. It allows producing the fullerene derivatives with high yields and selectivity.
