METHOD FOR SYNTHESIS OF VOLATILE LANTHANIDE PERFLUOROALKOXIDES Russian patent published in 2018 - IPC C07F5/00 C07C29/68 C07C31/28 

FIELD: chemistry.

SUBSTANCE: invention relates to a process for synthesis of perfluorinated lanthanide alkoxides that can be used in chemical vapour deposition techniques for the deposition of coatings with special properties, for doping semiconductors and for synthesis of superconducting materials, for separating complex mixtures of metals and for their deep purification from impurities. Method comprises treating a complex salt of a lanthanide, which uses aliphatic alkoxides of lanthanides of general formula (OC_nH_2n+1)₃Ln, where C_nX_2n+1 – a linear or branched alkyl radical for n = 3–4, a perfluorinated alcohol compound, which is trimethylfluoroalkoxysilane of general formula [(CH₃)₃SiOCR₁R₂R₃], where R₁, R₂, R₃ are CF₃ or C₂F₅, in an organic solvent medium while heating and subsequent removal of the solvent and volatile reaction products in a vacuum.

EFFECT: proposed method allows to obtain end products of high purity using a simple technique.
