Electrochemical fluorination of N-cyclopentylpyrrolidine gave the corresponding F-amine together with a ring-opened compound N-(F-pentyI)-F-pyrrolidine in the ratio of 1 to 1, in 55% yield. N-cyclohexylpyrrolidine, N-cyclopentylpiperidine, and N-cyclohexylpiperidine were also eletrochemically fluorinated in the same manner to give the corresponding F-amines, their isomers with rearranged structures

The invention belongs to medicobiological industry and refers to the composition, method of production and use of the means, based on perfluorocarbon emulsions, intended as the blood substitute means and other remedies. The essence of invention consists in creation of method and composition made from the mixture of two perfluorocarbons: fast eliminated (Sv-syu) and (or) slowly eliminated (Sc-sp), as perfluorodecaline (PFD) / perfluoromethyl-cyclo-hexylpiperidine (PFMCP), or PFD/perfluorotributylamine (PFTBA), or perfluorooctylbromide (PFOB)/PFMCP, or PFOB/PFTBA, or PFOB/PFD, or PFMCP/PFTBA in ratio from 1/1 to 10/10, respectively; or a mixture of three perfluorocarbons: two are fast eliminated (C8-C10) and one is slowly eliminated (C11-C12), or of one fast eliminated (C8-C10) and two slowly eliminated (C11-C12), as PFOB/PFD/PFMCP, or PFOB/PFD/PFTBA, or PFOB/PFMCT/PFTBA, or PFD/PFMCP/PFTBA in ratio from 1/1/1 to 10/10/10, respectively; or a mixture of four perfluorocarbons: two of them are fast eliminated (C8-C10) and two slowly eliminated (C11-C12) PFOB/PFD/PFMCP/PFTBA in ratio from 1/1/1/1 to 10/10/10/10, respectively; a mixture of perfluorocarbons in emulsion from 1% (0,5 vol.%) to 100% (50 vol. %) with average particle size 30-80 nm, is emulsified by proxanol-268 from 0,2% to 20% with molecular weight 6-12 thousand Da, has acceptable electrolytic solution.
