- Synthesis and application of oxalic acid monoester derivatives
-
The invention relates to synthesis and application of oxalic acid monoester-containing compounds as shown in a general formula (I) which is described in the specification. The compounds represent a broad-spectrum efficient insecticidal and bactericidal agent structure type. The oxalic acid monoester-containing compounds can well control aphids, plutella xylostella and spodoptera exigua when used as novel insecticidal bactericides; the compounds can also be used for preventing and treating cucumber brown blotch, cucumber bacterial angular leaf spot, cucumber fusarium wilt, cucumber downy mildew, cucumber powdery mildew, tomato bacterial leaf spot and rice sheath blight. R in the general formula (I) is as defined in the specification.

- Design, synthesis and insecticidal activities of novel N-oxalyl derivatives of neonicotinoid compound
-
Ten novel neonicotinoid derivatives containing N-oxalyl groups were designed and synthesized, and their structures were characterized by 1H NMR, MS, IR, elemental analysis and single crystal X-ray diffraction analysis. The insecticidal activities of the new compounds were evaluated. The results of bioassays indicated that some of these title compounds exhibited excellent insecticidal activities.

- Synthesis, crystal structure, and insecticidal activity of novel N-alkyloxyoxalyl derivatives of 2-arylpyrrole
-
Two series of novel N-alkyloxyoxalyl derivatives of 2-arylpyrrole were synthesized, and their structures were characterized by 1H NMR spectroscopy, elemental analysis, and single-crystal X-ray diffraction analysis. The insecticidal activities of the new compounds were evaluated. The results of bioassays indicated that some of these title compounds exhibited excellent insecticidal activities, and their insecticidal activities against oriental armyworm, mosquito, and spider mite are comparable to those of the commercialized Chlorfenapyr.
