Strategies for sustainable palladium catalysis

open access: yesCoordination Chemistry Reviews, 2021
Abstract Palladium is established both as an indispensable metal in modern synthetic chemistry and as a key component in catalytic converters and electronic equipment. The unrelenting demand for this metal increases both the financial and environmental cost, through mining, of this metal, rendering consumption unsustainable in its current form.

Detection of Palladium(I) in Aerobic Oxidation Catalysis [PDF]

open access: yesAngewandte Chemie - International Edition, 2017
AbstractPalladium(II)‐catalyzed oxidation reactions exhibit broad utility in organic synthesis; however, they often feature high catalyst loading and low turnover numbers relative to non‐oxidative cross‐coupling reactions. Insights into the fate of the Pd catalyst during turnover could help to address this limitation.

Catalysis with Palladium(I) Dimers [PDF]

open access: yesAngewandte Chemie International Edition, 2020
AbstractDinuclear PdIcomplexes have found widespread applications as diverse catalysts for a multitude of transformations. Initially their ability to function as pre‐catalysts for low‐coordinated Pd0species was harnessed in cross‐coupling. Such PdIdimers are inherently labile and relatively sensitive to oxygen.
