A process for producing a fluorine-containing 2,4-diol represented by the formula [4],
wherein R
1
represents a hydrogen atom or an acyclic or cyclic alkyl group having a carbon atom number of 1 to 7; R
2
represents an acyclic or cyclic alkyl group having a carbon atom number of 1 to 7, a phenyl group, or a substituted phenyl group; and R
1
and R
2
are optionally bonded to each other to form a ring, includes reducing a hydroxy ketone represented by the formula [3],
wherein R
1
and R
2
are defined as above, by hydrogen in the presence of a ruthenium catalyst.
