Synthesis and herbicidal activities of fluorine-containing 3-pyridylmethyl-2-phenyliminothiazolidine derivatives

A series of fluorine-containing 2-phenyliminothiazolidine derivatives were synthesized by a facile and mild method in high yields. The structures of all the title compounds were characterized by 1H NMR, IR and HRMS. The results of bioassay showed that most of target compounds exhibited efficient herbicidal activities against Echinochloa crusgalli, Sorghum vulgare, Digitaria sanguinalis, Eclipta prostrasta, Cucumis sativus and Brassica campestris at 50 mg L−1.
