Hexafluoro-2-butyne
Encyclopedia
Hexafluoro-2-butyne is the fluorocarbon
with the formula CF3C≡CCF3. HFB, as it is known also, is a particularly electrophilic acetylene
, hence a potent dienophile.
It is prepared by the action of sulfur tetrafluoride
on acetylenedicarboxylic acid and the reaction of KF
with hexachlorobutadiene.
Fluorocarbon
Fluorocarbons, sometimes referred to as perfluorocarbons or PFCs, are organofluorine compounds that contain only carbon and fluorine bonded together in strong carbon–fluorine bonds. Fluoroalkanes that contain only single bonds are more chemically and thermally stable than alkanes...

Alkyne
Alkynes are hydrocarbons that have a triple bond between two carbon atoms, with the formula CnH2n-2. Alkynes are traditionally known as acetylenes, although the name acetylene also refers specifically to C2H2, known formally as ethyne using IUPAC nomenclature...

Potassium fluoride
Potassium fluoride is the chemical compound with the formula KF. After hydrogen fluoride, KF is the primary source of the fluoride ion for applications in manufacturing and in chemistry. It is an alkali metal halide and occurs naturally as the rare mineral carobbiite...
