Recent achievements on the agricultural applications of thioether derivatives: A 2010–2020 decade in review

Abstract

Thioether derivatives, an important synthetic strategy in drug discovery, are acquiring more importance in plant protection field in recent years because of their broad spectrum of agricultural activities, such as antifungal, antibacterial, insecticidal, acaricidal, nematocidal, antiviral, herbicidal, and plant growthregulating activity. Thioethers and their analogues have been an area of great interest in recent years. This review summarizes the structure and agricultural activities of the thioether derivatives as reported in the literature that mainly covers the past 10 years from 2010 to 2020 as well as may contribute to a better understanding of thioether derivatives as efficient agricultural agents and provide some ideas on the development of novel pesticides.

Organosulphur and organoselenium compounds as emerging building blocks for catalytic systems forO-arylation of phenols, a C–O coupling reaction

“…Thioethers are important organosulphur ligands (Chart 3) having C-S-C functionality. 174 In general, they have been explored more than selenoether for the purpose of catalyst development. They rarely offer a tridentate mode for coordinating with metal.…”

Molecular Organosulphur, Organoselenium and Organotellurium Complexes as Homogeneous Transition Metal Catalytic Systems for Suzuki Coupling

“…Thioether ligands also have a similar À CÀ SÀ CÀ moiety which is found in pincer ligands. [127] However, unlike pincer ligands, ordinary thioethers do not offer tridentate coordination mode for binding with metal. They form strong bonds with soft metals and rarely with hard ones.…”

Combined Experimental and Computational Study on the Transformation of a Novel 1,3,4-Oxadiazole Thioether Nematicide in Aqueous Solutions

“…(2) evaluation of the isotopic pattern to obtain a plausible molecular formula; (3) the molecular formula followed the rule of the number of nitrogen atoms; (4) the mass error between the extra mass and molecular formula was <5 ppm; (5) retention time (t R ) tolerance was 0.1 min; and (6) the peak areas of tentative compounds showed meaningful time trends, that is, they gradually increased or decreased after increasing. After pre-identification with CD, the structure of the tentatively selected compounds was identified based on the following information: (1) double-bond equivalent (DBE), (2) MS 2 fragment ions, (3) mass data of 18 O-labeled products, and (4) theoretical analysis.…”
