Shuttle catalysis
Did you know?
Shuttle catalysis is used to describe catalytic reactions where a chemical entity of a donor molecule is transferred to an acceptor molecule. In these reactions, while the number of chemical bonds of each reactant changes, the types and total number of chemical bonds remain constant over the course of the reaction. In contrast to many organic reactions which exothermicity practically renders them irreversible, reactions operated under shuttle catalysis are often reversible. … WebMay 18, 2024 · A Shuttle Catalysis: Elucidating a True Reaction Mechanism Involved in the Palladium Xantphos-Assisted Transposition of Aroyl Chloride and Aryl Iodide Functional …
