Abstract
The present invention provides a method for producing an olefin represented by General Formula (II): RfCF═CH2 (II) (wherein Rf is defined as below), wherein the method includes the step of contacting a fluorohalide represented by General Formula (I): RfCF2CH2X (I) (wherein Rf is H(CF2)n (n=1 to 8) or F(CF2)n (n=1 to 8), and X is Br or I) with a metal in a reaction medium of a polar organic solvent, or a mixed solvent of water and a polar organic solvent to conduct a dehalogenation reaction.The production method of the present invention provides olefins in a highly selective manner at a low cost and high yield under relatively mild reaction conditions.
