PROCESS FOR PRODUCING A-FLUOROALDEHYDES

摘要

A production process of an ±-fluoroaldehyde according to the present invention includes reaction of an ±-fluoroester with hydrogen gas (H 2 ) in the presence of a ruthenium complex. It is possible in the present invention to allow relatively easy industrial production of the ±-fluoroaldehyde and to directly obtain, as stable synthetic equivalents of the ±-fluoroaldehyde, not only a hydrate (as obtained by conventional techniques) but also a hemiacetal that is easy to purify and is of high value in synthetic applications. The present invention provides solutions to all problems in the conventional techniques and establishes the significantly useful process for production of the ±-fluoroaldehyde.
