Rhodium-Catalyzed Asymmetric Functionalization of Quinoxalinium Salts
, 2023 We report a rhodium-catalyzed asymmetric addition of aryl and alkenyl boronic acids to quinoxalinium salts that generates dihydroquinoxalines with high enantioselectivity.

Rh(I) Complexes in Catalysis: A Five-Year Trend
Molecules, 2021 Rhodium is one of the most used metals in catalysis both in laboratory reactions and industrial processes. Despite the extensive exploration on “classical” ligands carried out during the past decades in the field of rhodium-catalyzed reactions, such as ...

The Highest Oxidation State of Rhodium: Rhodium(VII) in [RhO3]+
Angewandte Chemie International Edition, 2022 AbstractAlthough the highest possible oxidation states of all transition elements are rare, they are not only of fundamental interest but also relevant as potentially strong oxidizing agents. In general, the highest oxidation states are found in the electron‐rich late transition elements of groups 7–9 of the periodic table. Rhodium is the first element
