“…To the best of our knowledge, Stults, Friedman, and co-workers were the first to use synchrotron XAFS in a study of homogeneous catalysts using a Rh complex . Following this pioneering study, homogeneous catalysts involving Ti, V, Cr, Mo, Mn, Fe, Ru, Ni, Pd, Au, and Cu were studied by XAFS. Note that one of the authors succeeded in elucidating the mechanism of paramagnetic Fe-catalyzed Kumada–Tamao–Corriu coupling by a solution-phase XAFS analysis .…”
