| Abstract: | The tricyclic derivative was formed by the reaction of 1 ,5-diazabicyclo4,3,0] non -5-ene (DBN) and perfluoro-2-alkynoates. The products were analyzed in detail by 1H nuclear magnetic resonance (NMR),13C NMR and 2D NMR. Their chemical shifts and /-coupling constants were discussed. The reaction paths and mechanism were also proposed. |
