A method of producing a fluorine-containing compound, which contains the step of: fluorinating a substrate in a solvent with fluorine gas, wherein as said substrate, a substrate that cannot substantially undergo fluorinating reaction independently, is allowed to react, in the presence of a substrate that rapidly undergoes fluorinating reaction independently.

The present invention, which is aimed at providing a novel reaction for converting a fluorine-containing carbonyl compound to an asymmetric fluorine-containing primary amine, relates to a method in which a Schiff base obtained by the condensation of a fluorine-containing carbonyl compound and an asymmetric amine ((S)- or (R)-1-phenylethylamine) is treated in the presence of an appropriate organic base to hydrolyze a tautomeric imine obtained by asymmetrically performing an enzyme-like transamination reaction, yielding an asymmetric fluorine-containing amine.

Asymmetric fluorine-containing primary amines and their preparation

The object of the invention is to provide a novel process for epoxidation of perfluoro-olefins. This invention relates to a process for epoxidizing a perfluoro-olefin, characterized by employing a tertiary amine N-oxide represented by the general formula (I): ##STR1## (wherein R.sup.1, R.sup.2 and R.sup.3 each is a straight-chain or branched alkyl group having 1 to 10 carbon atoms, a lower alkyl group having 1 to 3 carbon atoms, or an aromatic group which may have a nitro group or a cyano group as a substituent; provided that all of R.sup.1, R.sup.2 and R.sup.3 are selected from the above alkyl groups, R.sup.1, R.sup.2 and R.sup.3 may combine with one another directly or through oxygen atoms or nitrogen atoms to form a cyclic compound of 5-7 membered ring), or iodosobenzene. According to the present invention, perfluoro-olefins can be converted to corresponding perfluoroepoxides cheaply and in high yields. Epoxides produced by the process of this invention are utilized as intermediates for syntheses of surface active agents, lubricant oils, water repellents, oil repellents, polymers, and the like.
