6. synthetic method as claimed in claim 5, which is characterized in that [60] molar ratio of fullerene and catalyst is 1:2.
7. synthetic method as described in claim 1, which is characterized in that the heating temperature of the reaction is 100~130 DEG C.
8. synthetic method as claimed in claim 6, which is characterized in that the heating temperature of the reaction is 120 DEG C.
9. such as the described in any item synthetic methods of claim 1-8, which is characterized in that concrete operations are as follows: firstly, in round-bottomed flask
Middle addition [60] fullerene, catalyst, 3- methylbutyraldehyd and primary amine, add chlorobenzene and keep reactant complete with Ultrasound Instrument ultrasound
Then the round-bottomed flask for filling reaction mixture is placed in heat in oil bath and react, after the reaction was completed by reaction mixture by dissolution
Short silicagel column coarse filtration is first passed through, solvent under reduced pressure steams, and residue chromatography column chromatography for separation, is elution with carbon disulfide later
Agent, what is be separated first is unreacted [60] fullerene to get [60] fullerene cyclopentene derivatives.
