Abstract
The present invention provides a method for producing a fullerene derivative, comprising the organic group addition step B in which an organic group is further added by reacting at least a basic compound and a halogen compound with a fullerene derivative, which is obtained by addition of a hydrogen atom and an organic group in the organic group addition step A, in which an organic group is added by reacting at least a Grignard reagent and a polar substance with a fullerene or fullerene derivative.
Claims21
A method for producing a fullerene derivative which is a mono(organo)fullerene derivative, a di(organo)fullerene derivative, a tri(organo)fullerene derivative or a tetra(organo)fullerene derivative comprising the organic group addition step A for adding an organic group by reacting at least a Grignard reagent and a polar substance with a fullerene or fullerene derivative, in which the polar substance having the donor number of 25 to 33.1 is used in an amount of 3 to 100 equivalents of the fullerene or fullerene derivative to which the organic group is added;
- wherein the polar substance is not pyridine.
