Synthesis and Herbicidal Activity of α-[2-(Fluorosubstituted phenoxy) propionyloxy]alkylphosphonates
Abstract:
In order to find new phosphonates with better herbicidal activity,fluorous group was introduced to α-oxophosphonates.Eight novel phosphonate derivatives were synthesized by the condensation reaction of 2-(fluoro-substituted phenoxy) propionyl chloride with α-hydroxyphosphonates in chloroform under reflux in yields of 20%~71%.The molecular structures of all the compounds were confirmed by IR,1H NMR and MS.Preliminary bioassay results show that some of these compounds have better inhibiting effect against the roots of monocotyledon and dicotyledon.Inhibitory rates of compounds Ⅲe~Ⅲh against the roots of rape and barnyard grass were more than 93%.
