METHOD FOR PREPARING FLUORINATED ESTER Russian patent published in 2007 - IPC C07C67/03 C07C67/287 C07C37/14 C07C69/708 

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to a method for synthesis of fluorinated ester. The process involves the re-esterification step wherein compound of the formula: R^AF-COOCF₂-R^AF and compound of the formula: R^A-CH₂OH are subjected for the re-esterification reaction in the molar ratio = 1:(1-2) to yield R^AF-COOCH₂-R^A, and the fluorination step wherein the synthesized compound is fluorinated with yielding the reaction product in the amount exceeding the mole amount before the re-esterification reaction and comprising compound of the formula: R^AF-COOCF₂-R^AF wherein R^A means a monovalent (C₁-C₂₀)-hydrocarbon group, monovalent halogen-containing (C₁-C₂₀)-hydroarbon group, monovalent heteroatom-containing (C₁-C₂₀)-hydrocarbon group or monovalent (C₁-C₂₀)-hydrocarbon group containing halogen atom and heteroatom, and R^AF means the same group as R^A group or monovalent hydrocarbon group prepared by fluorination of R^A group.

EFFECT: improved method of synthesis.
