A series of novel 5-(trifluoromethyl)-1 H-pyrazole-4-carboxamide derivatives (6a-6n,7a,7b,and 8a-8f)were synthesised by placing the amide bond at the 4-position of the pyrazole ring.These derivatives differed from the structure of chlorantraniliprole analogues with the amide bond at the 5-position of the pyrazole ring.Preliminary bioassay results revealed that a few title compounds exhibited good insecticidal activities against lepidopteran pests,such as Plutella xylostella,Mythimna separate,Heliothis armigera,and Ostrinia nubilalis.Some title compounds also elicited broad-spectrum insecticidal activities against dipterous insects including Culex pipiens pallens after altering the amide position.Similar to pyrazole-5-carboxamide analogues,compounds 6b and 6e showed 100% insecticidal activity against P.xylostella,C pipiens pallens,and M.separate at concentrations of 200,2,and 200 μg/mL,respectively.This finding suggested that 5-(trifluoromethyl)-1H-pyrazole-4-carboxamide derivatives are potential alternative insecticides for management of agriculture pests.
