Synthesis, Crystal Structure and Biological Activity of Novel Dichloroacetyl Oxazolidine Herbicide Safeners

摘要

A series of novel N-dichloroacetyl oxazolidine herbicide safeners was synthesized and characterized by IR, ~1H NMR, ~(13)C NMR, elemental analysis and X-ray diffraction. The preliminary biological test shows that the compounds could protect maize against injury caused by chlorsulfuron to a certain extent.
