Abstract

The present invention provides a novel method for producing a mixture of fluoroalkyl iodides with high production efficiency, the method enabling the production of a desired fluoroalkyl iodide with high selectivity. Specifically, the present invention provides a method for producing a mixture of fluoroalkyl iodides represented by formula (I):R(CFCF)I  (I)(wherein Rrepresents a fluoroalkyl group having 1 to 10 carbon atoms, and n is an integer indicating a degree of polymerization), the degree of polymerization n being m or more (m is an integer of 2 or more) by telomerization in metal catalyst-containing reactors, the method including:
