Various approaches are described for dehydrofluorination of heptafluorobut-2-ene (2) to give hexafluorobut-2-yne (1). Molecular sieve is particularly successful. Reaction of (2) with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) surprisingly gave the novel heterocycle (8) via initial nucleophilic attack. Reactions of (2) with other bases are also described.
