摘要：
Novel methods for preparing perfluoroalkanedi(sulfonyl chloride) are disclosed as are uses for these compounds. In one aspect, a method comprising reacting dibromoperfluoroalkane with Na2S2O4 followed by treating with chlorine, an organic compound, and then chlorine to form perfluoroalkanedi(sulfonyl chloride) is provided. Novel perfluoroalkanedi(sulfonyl bromide) compounds are also disclosed.
