Cyclobutene is a
cycloalkene. It is of interest in research but currently has no practical applications. It is a colorless easily condensed gas. A modern synthesis involves the 2-step dehydration of
cyclobutanol.
The compound was first prepared by
thermolysis of the ammonium salt
4H7NMe3H.
Cyclobutene thermally isomerizes to 1,3-butadiene. This strongly exothermic reaction reflects the dominance of ring strain. In contrast, the corresponding equilibrium for
hexafluorocyclobutene disfavors
hexafluorobutadiene.
