Document Type and Number:
Japanese Patent JP4538953
Kind Code:
B2
Abstract:
A compound having at least 4 carbon atoms and a -ClC=CF-group is hydrogenated in the liquid phase or the vapor phase in the presence of a noble metal catalyst to give a compound having at least 4 carbon atoms and a -CH2-CHF- group. The compound having at least 4 carbon atoms and a -ClC=CF- group is preferably an alicyclic compound having 4 to 10 carbon atoms, and is prepared by allowing a compound having at least 4 carbon atoms and a -ClC=CCl- group to react with a fluorinating agent.
