METHOD FOR PRODUCING FLUORINE-CONTAINING HYDROXYALDEHYDE, FLUORINE-CONTAINING PROPANEDIOL, AND FLUORINE-CONTAINING ALCOHOL MONOMER

摘要

PROBLEM TO BE SOLVED: To provide a production method which enables a fluorine-containing hydroxyaldehyde, a fluorine-containing propanediol which is a derivative thereof, and a fluorine-containing alcohol monomer useful as a resist raw material using the same to be obtained easily in high yield.SOLUTION: The method for producing a fluorine-containing hydroxyaldehyde comprises a step of reacting a fluorine-containing ketone represented by a formula (4) and an aldehyde represented by a formula (5) in the presence of an organic base selected from a heterocyclic compound containing a nitrogen atom in the ring or a tertiary amine to obtain a fluorine-containing hydroxyaldehyde represented by a formula (1). (Rf1 and Rf2 are represented by a trifluoromethyl group; and R2 and R3 are represented by H.)
