Provided is a device for generation of cyclopropene compounds which is capable of achieving direct in situ preparation and application of cyclopropene compounds inhibiting the action of ethylene which accelerates the ripening process of plants, the device comprising a first storage part for storing precursors of cyclopropene compounds (“cyclopropene precursors”), a second storage part for storing reaction reagents which convert cyclopropene precursors into cyclopropene derivatives via chemical reaction, and a spray part for spraying the cyclopropene derivatives produced by the chemical reaction between the cyclopropene precursors and the reaction reagents.

Intramolecular interaction of vinylcarbenes derived from 1,2-dichlorocyclopropenes with isoxazoles or bicyclic isoxazolines can lead to a rearrangement with the formation of 1-azafulvenes or derived 2-alkenoylpyrroles.
