Cyclopropenes and method for applying cyclopropenes to agricultural products or crops

摘要

Disclosed is a method for directly preparing in situ cyclopropenes for inhibiting ethylene action facilitating ripening and aging of plants via reaction of a cyclopropene precursor such as a compound of Formula (2) or Formula (3) with a fluoride (F−) and immediately applying the same to plants, and an aryl group-containing 1-alkylcyclopropene of Formula (6) effective for inhibiting the action of ethylene.

1. A method for treating plants with 1-alkylcyclopropene represented by Formula 1 below comprising:
mixing (i) a 1-alkylcyclopropene precursor-containing agent of Formula 2 or 3 and (ii) a fluoride-containing agent, separately supplied, to prepare 1-alkylcyclopropene of Formula 1; simultaneously or continuously with the mixing, phase-separating 1-alkylcyclopropene of Formula 1 from the reaction solution; and applying the 1-alkylcyclopropene of Formula 1 to plants, wherein the steps are carried out in situ; wherein A represents a straight-chain linkage having the formula of (CH2)mY(CH2)n, in which m and n each independently represent an integer of 0 to 3 and Y each independently represents CH2, O or S; R1 represents C4-C10 aryl, furanyl, pyranyl, or thiofuranyl, each of which may be substituted with at least one selected from the group consisting of fluoride, chloride, bromide, iodide, oxygen, sulfur, nitrogen and silicon; R2, R3 and R4 each independently represent saturated or unsaturated C1-C10 alkyl or alkoxy, C6-C10 aryl or aryloxy, C1-C10 primary amine or secondary amine, or halogen; and X represents halogen or OSO2T, in which T represents hydrogen, saturated or unsaturated C1-C10 alkyl, alkoxy or aryl, aryloxy, amine, halogen or hydroxy.
