Rhodium-Catalyzed Arene Alkenylation: Selectivity and Reaction Mechanism as a Function of In Situ Oxidant Identity.

ABSTRACT: Rhodium catalyzed arene alkenylation reactions with arenes and olefins using dioxygen as the direct oxidant (e.g., ACS Catal. 2020, 10, 11519), Cu(II) carboxylates (e.g., Science 2015, 348, 421; J. Am. Chem. Soc. 2017, 139, 5474) or Fe(III) carboxylate clusters (e.g., ACS Catal. 2024, 14, 10295), in the presence or absence of dioxygen, have been reported. These processes involve heating catalyst precursor [(η²-C₂H₄)₂Rh(μ-OAc)]₂, olefin, arene, and oxidant at temperatures between 120 and 200 °C. Herein, we report comparative studies of Rh-catalyzed arene alkenylation as a function of oxidant identity. This work includes comparisons of catalysis using Cu(
