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 a...
