Document Type and Number:

WIPO Patent Application WO/1999/033771

Kind Code:

A1

Abstract:

Compounds each having a -CH¿2?-CHF- group and a number of carbon atoms of 4 or above are prepared by hydrogenating a compound having a -CCl=CF- group and a number of carbon atoms of 4 or above in the presence of a noble metal catalyst in a liquid or gas phase. The compound having a -CCl=CF- group and a number of carbon atoms of 4 or above is preferably a C¿4?-C¿10? alicyclic one, and can be prepared by reacting a compound having a -CCl=CCl- group and a number of carbon atoms of 4 or above with a fluorinating agent.
