Abstract

The invention discloses application of 2-arylmorpholine as shown in the chemical structural formula I or salt thereof serving as an insecticide. The formula I is shown in the specification, wherein, R<2> is chosen from H, OH or OR<1>, and R<1> is chosen from C1-C2 alkyl and C3-C4 linear alkyl or branched alkyl; R<3> is chosen from H, C1-C2 alkyl and C3-C4 linear alkyl or branched alkyl; R<4> is chosen from H, C1-C2 alkyl, C3-C4 linear alkyl or branched alkyl, ethoxyl and benzyl; R<5> is chosen from H, C1-C2 alkyl, C3-C4 linear alkyl or branched alkyl, phenyl or substituted phenyl; Ar is chosen from phenyl, substituted phenyl or 6-methoxy-2-naphthyl; and the salt of the 2-arylmorpholine is chosen from hydrochloride, hydrobromate, sulphate, nitrate or phosphate.

Description

technical field [0001] The present invention relates to the application of a class of compounds as the preparation of insecticides, in particular to the application of 2-arylmorpholine and its salts as the preparation of insecticides. Background technique [0002] Shao Ling et al. described that 4-aryl-5-triazolylthiazole-2-imine compounds have fungicidal activity against Pleurotus spp. (Chemical Journal of Chinese Universities, 2007, 28, 270). He Daohang et al. described the synthesis and bactericidal activity of 4-aryl-2-(2-hydroxybenzimino)thiazole [Journal of South China University of Technology, Natural Science Edition, 2008, (3): 60]; Chinese patent (CN 101602761) describes The bactericidal activity of 4-tert-butyl-5-(1,2,4-triazol-1-yl)-2-benziminothiazole; Chinese patents (CN 101653127, CN 101632366) described a Alcohol or pyrimethol and morpholine fungicide pesticide composition, the pesticide composition has fungicidal activity on the prevention and treatment of a...
