Abstract:
This method for producing a fullerene derivative is a method for producing a fullerene derivative having a partial structure shown by formula (1) by reacting a predetermined halogenated compound and two carbon atoms adjacent to each other for forming a fullerene skeleton in a mixed solvent of an aromatic solvent and an aprotic polar solvent having a C═O or S═O bond in the presence of at least one metal selected from the group comprising manganese, iron, and zinc; (in formula (1), C* are each carbon atoms adjacent to each other for forming a fullerene skeleton, A is a linking group having 1-4 carbon atoms for forming a ring structure with two C*, in which a portion thereof may be a substituted or condensed group).
