, p. 49 - 53 (2021)
A rhodium-catalyzed oxidative annulation of benzimidates with elemental sulfur for the direct construction of isothiazole rings is reported. The proposed reaction mechanism involving Rh(I)/Rh(III) redox is supported by a stoichiometric reaction of metallacycle species as well as DFT calculations. This method is also applicable to selenium cyclization to produce isoselenazole derivatives. The alkoxy substituent at C3 can be used for further functionalization of the azole core.

Paragraph 0044-0045, (2020/06/08)
The present invention discloses an iridium complex represented by the following formula (1) and an organic electroluminescence device using the iridium complex as a phosphorescent dopant material. The phosphorescent dopant material may lower a driving voltage and power consumption and increase a current efficiency and half-life of the organic electroluminescence device. The same definition as described in the present invention.

The synthesis, isolation, and X-ray structure of a thioanisole-based trilithium complex are reported. On the basis of the double-lithiation strategy, two novel synthetic methodologies have been developed under mild reaction conditions (room temperature): (1) reactions of lithiated thioanisoles with nitriles give benzoisothiazoles via a [3 + 2]-type of approach with two new bond formations and (2) formation of benzothiophenes from thioanisoles and amides through a [4 + 1] pattern forming 4 new chemical bonds.
