    Abstract: A method of making α,ω-diiodoperfluoroalkanes includes combining: diatomic iodine, at least one perfluoroalkylene oxide represented by the formula wherein Rf represents a perfluoroalkyl group; and at least one of: a) a first metallic compound comprising nickel, and a second metallic compound comprising molybdenum that is compositionally different from the first metallic compound; or b) a metallic alloy comprising from 50 to 70 percent by weight of nickel and from 20 to 40 percent by weight of molybdenum, based on the total weight of the metallic alloy, thereby producing at least one product represented by the formula I(CF2)nI, wherein n independently represents an integer in the range of from 1 to 11. The total weight of the at least one product wherein n is 3 or greater exceeds the total weight of the at least one product wherein n is 1 or 2 by a factor of at least 4.

    Abstract translation: 制备α，ω-二碘全氟烷烃的方法包括组合：双原子碘，至少一种由下式表示的全氟氧化烯，其中Rf表示全氟烷基; 和至少一种：a）包含镍的第一金属化合物和包含与第一金属化合物成分不同的钼的第二金属化合物; 或b）金属合金，其包含基于金属合金的总重量的50-70重量％的镍和20至40重量％的钼，由此产生至少一种由式I表示的产物（CF 2 ）nI，其中n独立地表示1至11范围内的整数。其中n为3或更大的至少一种产物的总重量超过至少一种产物的总重量，其中n为1或2，其中n为1或2， 至少4的因素。
