PHOSPHORUS-CONTAINING DERIVATIVES OF FULLERENE C, AND THEIR PRODUCTION METHOD Russian patent published in 2014 - IPC C07F9/38 C07F9/40 

FIELD: chemistry.

SUBSTANCE: invention refers to fullerenes of formula 1 and to their production methods, which can be used in chemical industry and helioenergetics, , where X means the following: hydrogen atom or alkyl (C_nH_2n+1; n=1-20) radical, where R₁ means the following: hydrogen atom, alkyl (C_nH_2n+1; n=1-20), alkenyl (C_nH_2n+1; n=1-20) or alkynyl radical (C_nH_2n-3; n=1-20); residue of alkyl halide -(CH₂)_nHal (Hal=F, CI, Br, I), simple ether - (CH₂)_nOR'₁ or -(CH₂CH₂O)_nR'₁, for which n=0-20, and R'₁ is hydrogen atoms or linear or branched alkyl (C_mH_2m-1; n=1-20), alkenyl (C_mH_2m-1; n=1-20) or alkynyl radicals (C_mH_2m-3, n=1-20). The proposed method consists in the fact that an Arbusov reaction is performed, to which fullerene chloride C₆₀Cl₆ is added with the corresponding organic phosphites.

EFFECT: new fullerenes, which are suitable for being used in organic solar batteries, as well as a new effective method for their production, are proposed.
