A highly efficient electrochemical reduction of fullerene-fused lactones to fullerene-fused ketones, a formal process of retro Baeyer-Villiger reaction, has been achieved for the first time. The electrochemically generated dianionic fullerene-fused lactones can be transformed into fullerene-fused ketones in the presence of acetic acid in 85-91% yields. Control experiments have been performed to elucidate the reaction mechanism. The products have been characterized with spectroscopic data and single-crystal X-ray analysis. Moreover, the electrochemical properties have also been investigated.
