Polyhalogenoallenes. Part IV. Thermal co-dimerisation of tetrafluoroallene with hexafluorobut-2-yne
Abstract
Reaction of tetrafluoroallene with hexafluorobut-2-yne at 80—85° under autogenous pressure in the presence of free-radical scavengers yields, as major product, perfluoro-(1,2-dimethyl-3-methylenecyclobutene), the 19F nuclear magnetic resonance spectrum of which is discussed.
