Abstract:

Reaction of 1,8-diazabicyclo\[5,4,0\] undec-7-ene (DBU)  with perfluoro- 2-alkynoates yielded tricyclic derivatives. The products were analyzed by 1H NMR,   13C NMR and 2D NMR spectroscopy. The resonances in 1H NMR and 13C NMR spectra  were assigned, and the structures of the products were determined. The pathways  and the mechanism of the addition reaction were also discussed.

Key words: NMR DBU, perfluoroalkynoate, assignment
