Insertion of hexafluoropropene under thermal and/ or photochemical conditions occurs into C-H bonds of the halogenomethanes MeCl, CH2Cl2, CHCl3, MeF, CH2F2 and CHF2Cl and the fluoroethanes EtF, MeCHF2 and MeCF3, into CH and CCl bonds of the monochloroalkanes EtCl, MeCHFCl, prnCl, priCl, ButCl and BuiCl and into CCl bonds of allyl chloride and the chloroalkanes CH2ClCH2Cl, MeCHCl2, CH2ClCHCl2 and
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.
