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.

The active nickel complex generated in situ by reduction of NiBr2(PPh3)2 with zinc in the presence of Et4NI is a useful reagent for the dehalogenativecoupling of phenacyl halides to 1,4-diaryl-1,4-diketones and for the dechlorination of 3,4-dichlorobicyclo[4.2.0]-octane-2,5-diones to bicyclo[4.2.0]oct-3-ene-2,5-diones.

Methods of applying cyclopropene derivatives and compositions thereof to block ethylene receptors in plants are disclosed. One such method comprises applying to the plant an effective ethylene response-inhibiting amount of cyclopropene derivatives or compositions thereof. Also disclosed are methods of inhibiting abscission in plants, methods of prolonging the life of cut flowers, methods of inhibiting ripening of picked fruits, and methods of inhibiting ripening of picked vegetables.

2-Cyclopropene-1,1-dicarboxylic and Bicyclo[1.1.0]butane-2,2-dicarboxylic Diesters Cyclopropenation of bis[trimethylsilyl]-acetylene with diazomalonic esters affords 2,3-disilylated cyclopropene-1,1-dicarboxylic esters which are desilylated to 2-cyclopropene-1,1-dicarboxylic esters by treatment with potassium fluoride/crown ethers in acetonitrile. Two independent routes to silylated and non-silylated bicyclobutane-2,2-dicarboxylic esters are described.
