New fluorination of organic compounds using thermodynamically unstable nickel fluorides
摘要:
Replacement of hydrogen by fluorine in a variety of organic compounds is accomplished with high efficiency in liquid hydrogen fluoride (aHF), at or below 20 degrees C, using the thermodynamically unstable fluorides RNiF(3) and NiF4, the latter prepared in situ from K2NiF6 with BF3.

reactions of acyclic and cyclic alkanes with hexafluoropropene are described. A variety of perfluorocarbons and polyfluorinated alkenes, di-enes and a tetra-ene were synthesised from these polyfluoroalkylated alkanes. Elimination of hydrogen fluoride gives fluorinated alkenes, with unusual kinetic control of product formation and further fluorinations gave novel perfluorocarbons. X-Ray crystallography
