Design, synthesis and insecticidal evaluation of aryloxy dihalopropene derivatives

Plutella xylostella (P. xylostella) is a highly migratory, cosmopolitan species and one of the most important pest of cruciferous crops worldwide. Pyridalyl as a novel class of insecticides has good efficacy against P. xylostella. On the basis of the commercial insecticide pyridalyl, a series of new aryloxy dihalopropene derivatives were designed and synthesized by using Intermediate Derivatization Methods. Their chemical structures were confirmed by 1H NMR, high-resolution mass spectrum (HRMS), and single-crystal X-ray diffraction analysis. The insecticidal activities of the new compounds against P. xylostella were evaluated. The results of bioassays indicated that most of the compounds showed moderate to high activities at the tested concentration, especially compounds 10e and 10g displayed more than 75% insecticidal activity against P. xylostella at 6.25 mg/L, while pyridalyl showed 50% insecticidal activity at the same concentration. The field trials result of the insecticidal activities showed that compound 10e as a 10% emulsifiable concentrate (EC) was effective in the control of P. xylostella at 75-150 g a.i./ha, and the mortality of P. xylostella for treatment with compound 10e at 75 g a.i./ha was equivalent to pyridalyl at 105 g a.i./ha.

Process for the manufacture of diphenyl ethers

Hydroquinone mono-phenyl ethers, and their alkali metal salts of the formula STR1 in which one of the radicals R1 and R2 denotes trifluoromethyl and the other denotes hydrogen or halogen and R3 represents hydrogen or an alkali metal cation or ammonium cation are prepared by reacting hydroquinone bis-phenyl ethers (bisphenoxybenzenes) of the formula STR2 with hydroquinone derivatives of the formula STR3 in which Cat denotes an alkali metal cation or ammonium cation and R4 denotes an alkali metal cation or ammonium cation or a (C1 -C4)-alkyl group, in a polar aprotic solvent at temperatures from 120° to 280° C., and optionally, an alkyl group present in the R4 -position is split off by treatment with an acid.

Herbicidal diphenyl ethers

Diphenyl ethers of the formula STR1wherein R1 is hydrogen or halogen, R2 is hydrogen, halogen, or cyano, R is STR2 wherein R3 is hydrogen, halogen, nitro, alkyl, or alkoxy, R4 is a divalent alkylene radical, and R5 is cyano or -COR6, wherein R6 is alkoxy, hydroxy or salt thereof, allyloxy, alkoxyalkoxy, amino, alkyl or dialkyl amino, aminoalkoxy, or alkyl or dialkylaminoalkoxy, And diphenyl sulfides, sulfoxides, and sulfones of the formula STR3 wherein R8 is hydrogen, halogen, cyano, nitro, alkyl, alkoxy, or trifluoromethyl, R2 is hydrogen, halogen or cyano, X is sulfur, sulfinyl, or sulfonyl, and R is as defined above, And compositions containing these compounds exhibit herbicidal activity.

Phenyl ethers

Diphenyl ethers of the formula SPC1 Wherein R1 represents hydrogen or halogen and R2 hydrogen or a monovalent cation, are intermediates for the manufacture of selective herbicides.
