Rhodium-Catalyzed Arene Alkenylation Using Benzoquinone Derivatives as Oxidants.

ABSTRACT: The Rh-catalyzed conversion of olefins and arenes to alkenyl arenes using [(η²-C₂H₄)₂Rh-(μ-OPiv)]₂ as the catalyst precursor and 12 ortho- and para-substituted benzoquinone derivatives as the in situ oxidant is reported. Included are comparative studies of the quinone derivatives for (1) rate of styrene production from benzene and ethylene, (2) Markovnikov to anti-Markovnikov selectivity for reactions of benzene and propylene, and (3) ortho/meta/para selectivity when using tert-butylbenzene as the arene. Cyclic voltammetry was utilized to measure reduction potentials for each quinone to determine any possible influence of the quinone redox potential on arene alkenylation rate and selectivity. While significant differences in sel
