Background: A series of purinoxyphenoxypropionates were designed and synthesized by introducing 8-(trifluoromethyl)-9H-purine into the aryloxyphenoxypropionate backbone. Methods: The products were characterized by 1H NMR and HRMS. Results and Conclusion: Preliminary bioassays indicated that most of the compounds exhibited good herbicidal activity at 200 mg/L.
