Patent ID: 7041625

Claim:
A method of inhibiting an ethylene response in a plant comprising the step of contacting the plant with an effective ethylene response-inhibiting amount of a cyclopropene derivative of formula I or II: or a mixture thereof, wherein: a) each R 2 , R 3 , and R 4 is independently a group of the formula: -(L) n -Z wherein: i) n is an integer from 0 to 12 and p is an integer from 3 to 10; ii) each L is independently selected from a member of group D, E, or J wherein: D is of the formula: E is of the formula: J is of the formula: wherein: A) each X and Y is independently a group of the formula: -(L) m -Z; and B) m is an integer from 0 to 8; and C) no more than two E groups are adjacent to each other and no J groups are adjacent to each other; iii) each Z is independently selected from: A) hydrogen, halo, cyano, nitro, nitroso, azido, chlorate, bromate, iodate, isocyanato, isocyanido, isothiocyanato, pentafluorothio, or B) a group G, wherein G is an unsubstituted or substituted; unsaturated, partially saturated, or saturated; monocyclic, bicyclic, tricyclic, or fused; carbocyclic or heterocyclic ring system wherein; 1) when the ring system contains a 3 or 4 membered heterocyclic ring, the heterocyclic ring contains 1 heteroatom; 2) when the ring system contains a 5, or more membered heterocyclic ring or a polycyclic heterocyclic ring, the heterocyclic or polycyclic heterocyclic ring contains from 1 to 4 heteroatoms; 3) each heteroatom is independently selected from N, O, and S; 4) the number of substituents is from 0 to 5 and each substituent is independently selected from X b) the total number of non-hydrogen atoms in each compound is 50 or less; its enantiomers, stereoisomers, salts, and mixtures thereof; or a composition thereof.
