Kurose, Ryo,Nishii, Yuji,Miura, Masahiro
, p. 2380 - 2385 (2021/04/05)
Herein we report an efficient synthetic method for the electrophilic trifluoromethylthiolation of aromatic compounds. The key is to use triptycenyl sulfide (Trip-SMe) and TfOH to enhance the electrophilicity of SCF3 fragment through the formation of sulfonium intermediates. This method enables direct installation of an SCF3 group onto unactivated aromatics at room temperature, adopting a commercially available saccharin-based reagent. Preliminary DFT calculation was carried out to investigate the substitution effect on the catalytic activity.

Paragraph 0027; 0029; 0030; 0031, (2018/09/21)
The invention relates to a technical field of drug synthesis, in particular to a 3 - methyl - 4 - (4 - trifluro sulfide) oxy nitrobenzene industrial synthetic method, to 4 - trifluro sulfur phthalimidephenol and 2 - chloro - 5 - nitro-toluene as the raw materials, to potassium carbonate as acid-binding agent, to dimethyl sulfoxide as solvent, in order to toluene as the water removal, 120 - 140 °C reflow reaction to obtain the 3 - methyl - 4 - (4 - trifluro sulfide) oxy nitrobenzene. This invention adopts the toluene - water azeotropic temperature higher than the reaction temperature of the reflow reaction, using toluene and water azeotropy principle, so that the moisture free from the reaction system, thus promoting the reaction; the reaction yield from the existing method of 85% has been raised to about 97 - 98%, and the product does not need to be purified can be put into the next step reaction.

An environmentally benign and selective electrochemical oxidation of sulfides and thiols in a continuous-flow microreactor

supporting information, p. 4061 - 4066 (2017/09/07)
A practical and environmentally benign electrochemical oxidation of thioethers and thiols in a commercially-available continuous-flow microreactor is presented. Water is used as the source of oxygen to enable the oxidation process. The oxidation reaction utilizes the same reagents in all scenarios and the selectivity is solely governed by the applied potential. The procedure exhibits a broad scope and good functional group compatibility providing access to various sulfoxides (15 examples), sulfones (15 examples) and disulfides (6 examples). The use of continuous flow allows the optimal reaction parameters (e.g. residence time, applied voltage) to be rapidly assessed, to avoid mass- and heat-transfer limitations and to scale the electrochemistry.
