    摘要: A process is disclosed for producing RCFZH by reaction of an iodide compound of the formula R′CFZI with hydrogen at an elevated temperature, wherein R is SF5, CF2SF5 or RfCF2Y, R′ is SF5, CF2SF5 or RfCF2X, Rf is a perfluoroalkylene group containing from 1 to about 12 carbon atoms and optionally containing one or more ether oxygen atoms, Z is selected from F, CF3 and CF2CF3, Y is selected from H, F and SF5, and X is selected from H, F, SF5, and I, provided that when Y is F, X is F, when Y is SF5, X is SF5, and when Y is H, X is H or I.
