Page/Page column 4, (2011/12/12)
The present invention provides a method for the preparation of suitable chlorofluorocarbon and hydrochlorofluorocarbon materials or chlorofluorocarbon and hydrochlorofluorocarbon alkene and alkyne intermediates which serve as useful feedstock for fluorination and reduction to cis-1,1,1,4,4,4-hexafluoro-2-butene. Also presented is a continuous process for the production of cis-1,1,1,4,4,4-hexafluoro-2-butene from the alkene and alkyne intermediates.
THE FLUORINATION OF BUTANE OVER COBALT TRIFLUORIDE

The fluorination of butane over cobalt trifluoride has given a complex mixture of partially fluorinated compounds: 51 of these have been identified, comprising over 99percent of the products.Most were polyfluor-butanes but 1-2percent were polyfluoro-2-methylpropanes.The reaction has no synthetic utility.There was some selectivity in the fluorination: secondary C-H was convertart byed into C-F more easily then primary, and the ease of replacement of a particular H was reduced by geminal vicinal fluorines.A computer model of the fluorination was only partially successful, perhaps because the fluorination proceeded in part by simple F for H replacement and in part via alkenes: the model only allowed for the former.
