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.

Iodination of selected 1-allyl- or 1-benzyl-cyclopropenes with electron-donating groups on the substituent leads to 2-iodo-1-iodomethyl-1 -vinyl or 1-arylcyclopropanes.

Neighbouring-group Influence on the Ring Opening of Some 2-Alkyl-1,1,2-tribromocyclopropanes under Phase-transfer Conditions

Several 2-alkyl-1,1,2-tribromocyclopropanes were treated with sodium hydroxide and ethanol under phase-transfer conditions. Ring opening gave mixtures of the corresponding acetylenic diethyl ketals and acetals. When the steric bulk of the alkyl substituent was increased acetal formation dominated, and in the case of 1,1,2-tribromo-2-(tert-butyl)cyclopropane, the acetal was formed as the only product.
