PURPOSE : A method for producing fluoroiodoalkane compounds is provided to improve catalyst performance and reaction rate by using a catalyst promoter. CONSTITUTION : A method for producing a fluoroiodoalkane compound represented by the formula of CF3(CF2)n-I(wherein, n is 0 or 1) includes a step of contacting (i) a compound, (ii) an iodine supply source, (iii) an alkali or alkaline earth metal salt catalyst supported on a carrier, and (iv) a catalyst promoter for the alkali or alkaline earth metal salt catalyst for time and at temperature sufficient to produce the fluoroiodoalkane compound. The compound(i) is represented by the formula of CF3(CF2)n-Y, wherein Y is selected from the group comprising H, Cl, Br, and COOH, and n is 0 or 1. The catalyst promoter comprises at least one element selected from the group comprising transition metal elements, rare earth metal elements, main group elements other than alkali or alkaline earth metal elements, salts thereof, and combinations thereof. © KIPO 2008
