摘要：
A substituted phenoxyethyl(isopropyl)acyloxyalkyl phosphonate having phosphorusheterocyclic ring and having herbicidal activity, with a general formula of I, wherein R represents 5,5-dimethyl-1,3,2-dioxaphosphorinan-2-one-2-yl, or 1-oxo-1-phospha-2,6,7-trioxabicyclo[2,2,2]octan-4-yl, or 1-sulfo-1-phospha-2,6,7-trioxabicyclo 2,6,7-trioxabicyclo[2,2,2]octan-4-yl R1 represents H, C1-C4 alkyl, phenyl, furyl, pyridyl, or phenyl substituted with methyl, methoxyl, nitro or chloro R2 represents H, methyl, and methyl only if R in the general formula I is 1-sulfo-1-phospha-2,6,7-trioxabicyclo[2,2,2]octan-4-yl as phosphorusheterocyclic ring X and Y represent H, halogen, C1-C4 alkyl or trifluoromethyl, and X and Y are the same or different. The compounds according to the present invention may be used as active component of dicotyledonous broadleaf weed herbicides.
