Title:
PRODUCTION OF UNSATURATED COMPOUND CONTAINING FLUORINE
Document Type and Number:
Japanese Patent JPH08176032
Kind Code:
A
Abstract:

PURPOSE: To efficiently obtain the subject compound, useful as a raw material for industrial materials having excellent water and oil repellencies, mold releasability, etc., and capable of especially readily providing a silicone compound containing fluorine according to a specific method.

CONSTITUTION: A compound of the formula Rf-Q-X (Rf is a monovalent organic group containing fluorine; Q is a single bond or a bivalent organic group; X is Cl, Br or Cl) is reacted with a compound of formula I (R1 to R5 are each H or a monovalent organic group), preferably in the presence of azobisisobutyronitrile which is a radical initiator to afford a compound of formula II. XY are then eliminated from the resultant compound of formula II by heating in the presence of zinc in an amount of 1.1-1.5mol based on 1mol compound. Thereby, the objective compound of formula III is obtained. Furthermore, the compound of formula I is preferably used in an amount of 1-1.5mol based on 1mol compound of the formula Rf-Q-X.
