PROBLEM TO BE SOLVED: To provide an efficient method for producing a methanofullerene derivative suitable for mass production, and a sulfone compound which can be suitably used in the method. SOLUTION: The method for producing a [6,6] methanofullerene derivative according to the present invention includes a step of reacting a sulfone compound represented by the following formula (I) with fullerene in a solvent in the presence of a base. It is characterized by. [In the formula, R 1 indicates a C 1-30 alkyl group or the like which may have a substituent , R 2 indicates a C 6-30 aryl group or the like which may have a substituent, and R 3 Is H, or -X-C (= O) O-R 4 (in the formula, X indicates a single bond or a C 1-10 alkanediyl group, and R 4 may have a substituent C 1- 30 Indicates an alkyl group, etc.). ] [Selection diagram] None |
