Abstract:
This invention relates to fluoride substituted abscisic acid derivatives of formula (I) wherein R is alkyl group of C1-C2, X is H2 or O, and Y is H or OH. A fluoride replaced abscisic acid derivative is produced by witting reaction of triethyl 2-fluorophosphonoacetate with alpha-ionone. Fluoride replaced abscisic acid (ABA) derivatives are more stable than natural ABA and have strong physiological activity, so they can be used as a active ingredient of plant growth regulators such as herbicides or dwarfing chemicals.
