A series of N2S2-Cu(II) complexes based on N,N′-bis(alkylthiocarbamate)butane-2,3-diimine ligands have been synthesized and characterized by spectroscopic, electrochemical, and single crystal X-ray diffraction methods. This class of ligands contains a conjugated N2S2chelate framework with a non-coordinating, terminal alkoxy (–OR) group. Ligands and Cu(II) complexes were investigated for R = Me, Et,nPr,iPr, and octyl. Additionally, N,N′-bis(ethylthiocarbamate)hexane-3,4-diimine and its Cu(II) complex were analyzed. Single crystal X-ray diffraction studies on all six Cu(II) complexes confirm a square planar Cu(II) environment with no significant changes in the core structure as a function of R. Spectroscopic studies are consistent with a similar electronic environment in all complexes. However, electrochemical investigations reveal significant shifts in the CuII/Iand CuIII/IIreduction potentials throughout the series. The complexes are analogues of the well-known bis(thiosemicarbazone) Cu(II) which contain a similar donor core with terminal, non-coordinating amines. Substitution of the terminal amines of bis(thiosemicarbazones) with the alkoxy groups of N,N′-bis(alkylthiocarbamate)butane-2,3-diimines allows tuning of redox potentials with minimal changes in the physical and electronic structure.

A new library of 1,3,4-thiadiazole-containing pyrazole oximes was designed and synthesized. Their acaricidal and insecticidal activities were evaluated. Bioassay results indicated that some target compounds exhibited good acaricidal and insecticidal properties. Especially, compound 8m had 80% acaricidal activity against Tetranychus cinnabarinus at the concentration of 50?μg/mL, compound 8f displayed 100% insecticidal activities against Aphis craccivora at the concentration of 50?μg/mL, compounds 8r and 8w showed 100% insecticidal activities against Plutella xylostella at the concentration of 50?μg/mL. Furthermore, compounds 8r (LC50?=?19.61?μg/mL) and 8w (LC50?=?9.78?μg/mL) possessed comparable or even better insecticidal activities than the control Pyridalyl (LC50?=?17.40?μg/mL) against P. xylostella.
