Abstract
The present invention provides a process for the preparation of a fluoroiodoalkane compound represented by the formula CF(CF)—I, wherein n is 0 or 1. The process includes the step of contacting: (i) a compound represented by the formula CF(CF)—Y, wherein Y is selected from H, Cl, Br, and COOH and n is 0 or 1; (ii) a source of iodine; (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. The catalyst promoter includes at least one element selected from a transition metal element, a rare earth metal element, a main group element other than the alkali or alkaline earth metal element, any salts thereof, and any combinations thereof. The contacting is carried out at a temperature and pressure and for a length of time sufficient to produce the fluoroiodoalkane compound. The contacting may be carried out in the presence or absence of a solvent and in the presence or absence of oxygen.
