Synthesis of perfluorinated ketones by utilizing liquid-phase direct fluorination

A new synthetic procedure for the preparation of perfluorinated ketones from nonfiuorinated sec-alcohols was developed. A key step in the synthetic route was a liquid-phase direct fluorination reaction with elemental fluorine. Direct fluorination of a partially fluorinated ester, which was prepared from a nonfiuorinated sec-alcohols and a perfluorinated acyl fluoride, followed by thermal elimination, gave a perfluorinated ketone and the starting perfluorinated acyl fluoride, which could be recycled. Application to the synthesis of a precursor polyfluoroketone for fluoropolymer resists for 157nm microlithography was also established.

PROCESS FOR PRODUCTION OF FLUORINATED SULFONYL FLUORIDES

The present invention provides a process for producing a fluorinated sulfonyl fluoride useful as e.g. a material for an ion exchange resin, and a novel chemical substance useful as an intermediate in the production process. That is, to provide a process comprising oxidizing Y-S-RA-E-RB by means of an oxidizing agent essentially containing a halogen atom to obtain XSO2-RA-E-RB, and in a case that X is a fluorine atom, reacting the compound with fluorine in a liquid phase as it is, and in a case that X is a halogen atom other than a fluorine atom, converting X into a fluorine atom, and then reacting the obtained compound with fluorine in a liquid phase to obtain FSO2-RAF-EF-RBF, and then decomposing it to obtain FSO2-RAF-COF (wherein RA is a bivalent organic group such as an alkylene group, RB is a monovalent organic group such as a perfluoroalkyl group, E is -CH2OCO-, Y is a monovalent organic group such as a cyano group or the like, X is a halogen atom, RAF is a bivalent organic group having RA fluorinated or the like, RBF is the same group as RB or the like, and EF is -CF2OCO-).

NOVEL FLUORINATED ADAMANTANE DERIVATIVE

A novel fluorinated adamantane derivative. It is a compound represented by the formula AF(-COF)n, wherein AF means a fluorinated adamantane residue which is an n-valent group formed by removing n hydrogen atom(s) from adamantane (provided that when n is 2 or larger, then the hydrogen atoms to be removed are bonded to different carbon atoms) and in which at least one of the remaining hydrogen atoms may be replaced with a fluorine atom and the still remaining hydrogen atom(s) may be replaced with a C1-6 alkyl or fluoroalkyl group; and n is an integer of 1-4, provided that when n is 1, then the AF has at least one hydrogen atom.
