DBU 1 reacts as a (1,3) difunctional nucleophile with 2-H heptafluorobut-2-ene 2, giving the unusual product 8; a mechanism for the formation of 8 is proposed and an X-ray crystal structure of 8 is described.

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.
