Reaction and sensing of octafluorocyclopentene with 1,5-diazabicyclo [4,3,0]non-5-ene

Reactions of octafluorocyclopentene (C5F8) with 1,5-diazabicyclo[4,3,0]non-5-ene (DBN) are studied by analyses of an isolated product and optical spectra from the viewpoint of applications to gas-sensors. Obtained results suggest that nucleophilic reactions of DBN proceed toward the double bond of C5F8 molecule accompanied with hydroxide anion attack on carbon-fluoride bonds of C5F8 moiety under ambients, forming, unique C5F8-modified adducts. The present reaction is conducive to a new type of technologies for quick and selective sensing that can be used to develop alarm systems in the field of the environment and etching processing factories.
