Electronic Effects of Bidentate ,-Ligands on the Elementary Steps of Au(I)/Au(III) Reactions Relevant to Cross-Coupling Chemistry.

Oxidant-free Au(I)/Au(III)-catalyzed cross-coupling has been recently enabled by the use of bidentate ,-ligands. To further develop these ,-ligands, computational studies were performed to understand their effects on the oxidative addition of aryl iodide electrophiles with Au(I). Using this mechanistic understanding, six new electron-rich ,-ligands were synthesized.

Social distancing mediates clinical work and depression: impact of the COVID-19 pandemic on nurses.

Background: The psychological well-being of nurses, during the COVID-19 pandemic has become a critical area of concern. This study examines the psychological impact of the pandemic on nurses, focusing on the mediating role of perceived social distance between work units and depression.

Methods: This study employed a cross-sectional design with respondent driven sampling.
