ABSTRACT:
A method for producing a fluorine-containing organic compound represented by the formula (7):in-line-formulae description="In-line Formulae" end="lead"?R—Fm (7)in-line-formulae description="In-line Formulae" end="tail"?wherein R represents a substituted or unsubstituted saturated hydrocarbon group, or a substituted or unsubstituted aromatic group and m represents an integer satisfying the inequality: 1≦m≦n,which comprises reacting a fluorinating agent represented by the formula (1):wherein R1and R3are the same or different, and represent an optionally substituted alkyl group, R2, R4and R5are the same or different, and represent a hydrogen atom or an optionally substituted alkyl group, x satisfies 0<x≦1, and Y−represents a monovalent anion other than a fluoride ion,with an organic compound of the formula (6):in-line-formulae description="In-line Formulae" end="lead"?R-Ln (6)in-line-formulae description="In-line Formulae" end="tail"?wherein R is the same as defined above, L represents a leaving group and n represents an integer of 1 or more, and a fluorinating agent using the same are described.
