A monomer design strategy based on a bridged bicyclic thiolactone that produces stereo-disordered to perfectly stereo-ordered polythioesters is disclosed. The described polythioesters exhibit high crystallinity and full chemical recyclability. Such polymers possess intrinsic tacticity-independent crystallinity and chemical recyclability, tunable tacticities from stereo-disorder to perfect stereoregularity, as well as combined high-performance properties such as high thermal stability and crystallinity, and high mechanical strength, ductility and toughness.

A method for manufacturing an insecticidal compound and insecticidal compositions comprising the insecticidal compound and methods of use are presented herein. The manufacturing method presented herein allows for a high purity grade of thiocyclam hydrochloride to be synthesized. The insecticidal compositions comprising the thiocyclam hydrochloride can be used for prevention of crop destruction by insects. The use of thiocyclam hydrochloride in insecticidal compositions as described herein can achieve greater efficacy than previously known insecticides, by eliminating the insect pests more reliably and efficiently.

Disclosed is a method for producing a trisulfide compound or a selenotrisulfide compound. This production method includes: a step for oxidizing a disulfide compound with an oxidizing agent to obtain a sulfoxide compound; and a step for reacting the sulfoxide compound that has been obtained with a source of sulfur or a source of selenium to obtain a trisulfide compound or a selenotrisulfide compound.

A new strategy to design container molecules is presented. Sulfonylcalix[4]arenes, which are synthetic macrocyclic containers, are used as building blocks that are combined with various metal ions and tricarboxylate ligands to construct metal-organic ‘super-containers’ (MOSCs). These MOSCs possess both endo and exo cavities and thus mimic the structure of viruses. The synthesis of MOSCs is highly modular, robust, and predictable.

Disclosed herein is a novel method for preparing cyclophanes, comprising forming a disulfide cyclophane by contacting a linker moiety which includes two or more thiol groups, with a metal salt and an oxidant. The disulfide cyclophane is then desulfurized to form a thiacyclophane comprising thioether bridges. This thiacyclophane optionally may be further desulfurized to form an unsaturated hydrocarbon cyclophane, which can then be reduced to form a saturated hydrocarbon cyclophane. The various cyclophanes can be synthesized in a ring form, such as a dimer, trimer or tetramer etc., or they can be synthesized in a tetrahedral or larger structure. Also disclosed are novel cyclophanes formed by the disclosed method.
