Regioselective Electrosynthesis of Rare 1,2,3,16‐Functionalized [60]Fullerene Derivatives

Abstract

Fullerene derivatives with different addition patterns exhibit different physical, chemical, and biological properties, which are important for fullerene applications. Novel and rare 1,2,3,16‐functionalized [60]fullerene derivatives having a five‐membered heterocycle fused to a [5,6]‐junction were obtained with high regioselectivity by electrochemical derivatization of a [60]fulleroindoline. The product structures were determined by spectroscopic data and single‐crystal X‐ray analysis. The obtained high regioselectivity was rationalized using theoretical calculations.
