PREPARATION METHOD FOR FLUORINE-CONTAINING OLEFINS HAVING ORGANIC-GROUP SUBSTITUENTS

Document Type and Number:

WIPO Patent Application WO/2012/121340

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide a preparation method which enables the easy and efficient (high yield, high selectivity, low cost) preparation of fluorine-containing olefins having organic-group substituents, from fluorine-containing olefins. [Solution] A preparation method for fluorine-containing olefins having organic-group substituents, said method being characterised by including a process in which fluorine-containing olefins and an organic zinc compound are reacted in the absence of a transition metal catalyst.
