A monoethanolamine based Co(ii)-metallohydrogel can act as a Schottky barrier diode device and a catalyst for single-pot aryl–S bond formation at room temperature.
Reaction of diphenyl disulfide and aryl iodides or diiodides at high temperature affords phenyl aryl sulfides or bis(phenylthio)arenes in good yields. Thermolysis of dialkyl disulfide with aryl iodides yields only diarylsulfides.

Highly selective coupling of diiodoarenes with phenols or phenthiols can be performed by using a low-cost, benign character and readily available Fe/Cu catalytic system in the absence of ligands. It is noteworthy that the desired dimeric aryl ethers or sulfides could be obtained in high yields by coupling between diiodoarenes and phenols, or diphenols with aryl iodides.
Provided is a sulfonium salt manufacturing method which can reduce the production of a monosulfonium salt. A method of manufacturing a sulfonium salt includes preparing a first sulfonium salt containing a sulfonium cation and a first anion, preparing a second sulfonium salt by exchanging the first anion for a halide ion, and preparing a third sulfonium salt by exchanging the halide ion for a second anion.
