FIELD: industrial organic synthesis.
SUBSTANCE: invention relates to a method for preparation of multivalent carbonyl compounds and to a novel polyvalent carbonyl compound, which may be useful, for example, as intermediate in production of various fluorinated compounds. Polyvalent carbonyl compound is prepared through economically advantageous way from inexpensive substances and with no need of using any complex synthesis stage. In particular, polyvalent alcohol, including alcohols with at least two structures selected from primary, secondary, and tertiary structures, is brought into reaction with acid halide to form polyvalent ester, which is then fluorinated in liquid phase to form perfluorinated polyvalent ester, in which ester bonds, provided by reaction with primary and secondary alcohols, are further cleaved.
EFFECT: expanded synthetic possibilities in organofluoric compound area.
