Abstract

The invention belongs to the technical field of chemical synthesis, particularly relates to a N-methyl-2-(4-nitrobenzene vinyl)-3,4-fullerene pyrrolidine derivative, and further discloses a preparation method of the fullerene pyrrolidine derivative. The method for preparing N-methyl-2-(4-nitrobenzene vinyl)-3,4-fullerene pyrrolidine comprises the steps that the existing 1,3-dipolar-cycloaddition reaction is utilized, methylbenzene is used as a solvent for a reaction, and the target product N-methyl-2-(4-nitrobenzene vinyl)-3,4-fullerene pyrrolidine is obtained. It is surprised to find that after the whole reaction system is cooled to indoor temperature, an organic solvent comprising trichloromethane, carbon disulfide and orthodichlorobenzene is added, the reaction continues to be carried out to the end, the synthetic yield of the product is far higher than that of the product obtained through the solvent only comprising methylbenzene, and the unexpected technical effect is obtained.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, specifically relates to an N-methyl-2-(4-nitrostyryl)-3,4-fullerene pyrrolidine derivative, and further discloses a preparation method thereof. Background technique [0002] In 1985, when scientists such as R.F.Crul, R.E.Smallay and H.W.Kroto of the United Kingdom used high-energy laser pulses to graphite, they accidentally discovered a series of carbon ion clusters represented by C60, which were later called fullerenes or football enes. Fullerene thus stands out as the third allotrope of carbon. Later, inspired by the vaulted dome designed by architectural designer Buckminster Fuller, Kroto and others finally determined that C60 has a closed spherical cage structure similar to the vaulted dome, which is consistent with the "stable" nature of C60 match. [0003] [0004] Fullerene is the third allotrope of carbon. Its unique three-dimensional spherical space structure and numerous...
