FIELD: industrial organic synthesis.
SUBSTANCE: invention relates to industrially useful fluorine-containing compounds such as fluorinated ester compounds and acyl fluoride compounds. Invention, in particular, provides ester compound wherein all C-H groups are fluorinated and which is depicted by general formula RAFCFR1FOCORBF (4), where RAF, CFR1, and RBF are specified elsewhere. Preparation of the ester compound comprises fluorination of ester (4), which has hydroxyl group(s), acyl fluoride group(s) and which has a structure allowing compound to be fluorinated in liquid phase, fluorination being effected in mixture of ester compound and compound having acyl fluoride group(s). Method does not involve environmentally unfriendly solvent such as, for instance, R-113.
EFFECT: enabled fluorination requiring no specific solvent for each reaction and which can be carried out without separation of solvent before next stage.
