    摘要: Provided are methods for producing fluorinated organic compounds, which preferably comprises converting at least one compound of formula (I) CH2XCHZCF3 to at least one compound of formula (II) CHX═CZCF3 where X and Z are independently H or F, with the proviso that X and Z are not the same. The converting step comprises catalytically reacting at least one compound of formula (I), preferably via dehydrogenation or oxidative dehydrogenation. In another aspect, the inventive method of preparing fluorinated organic compounds comprises converting a reaction stream comprising at least one pentafluoropropene to a product stream comprising at least one pentafluoropropane and at least one compound of formula (I), separating out the compound of formula (I) from the product stream, and converting the compound of formula (I) separated from the product stream to at least one compound of formula (II), wherein the conversion the compound of formula (I) to 3,3,3-trifluoropropyne is substantially limited.
