Disclosed are 1,3-thiazetidine derivatives according to the formulae 2 or 3, wherein: N1, N2 and N3 are nitrogen atoms; Ar1 and Ar2 are independently optionally substituted furanyl, phenyl, pyridazinyl, pyridyl, pyrimidinyl or thienyl; Het is a 5 or 6 membered, saturated or unsaturated, heterocyclic ring, containing one or more heteroatoms independently selected from nitrogen, sulfur, or oxygen, and where Ar1 and Ar2 are not ortho to each other (but may be meta or para, such as, for a five membered ring they are 1,3 and for a 6 membered ring they are either 1,3 or 1,4), and where said heterocyclic ring may also be substituted with one or more substituents; R5 is an optionally substituted 1 membered saturated hydrocarbyl linkage; and wherein the remaining substituents are as defined herein. Representative compounds include (Z)-3-(2,6-difluorophenyl)-2-((E)-(4-(1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazol-3-yl)benzylidene)hydrazono)-1,3-thiazetidine, (Z)-3-(2-isopropylphenyl)-2-((E)-(4-(1-(4-(pentafluoroethoxy)phenyl)-1H-1,2,4-triazol-3-yl)benzylidene)hydrazono)-1,3-thiazetidine, and (Z)-3-(4-methoxy-2,6-dimethylphenyl)-2-((E)-(4-(1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazol-3-yl)benzylidene)hydrazono)-1,3-thiazetidine. Further disclosed is a composition comprising a compound as defined above, and optionally at least one other compound selected from the Insecticide Group, Acaricide Group, Nematicide Group, Fungicide Group, Herbicide Group, AI Group, or Synergist Group; for controlling pests such as Beet Armyworm, Com Earworm or Green Peach Aphid. |
