Solid–state molecular organometallic chemistry. Single–crystal to single–crystal reactivity and catalysis with light hydrocarbon substrates by Chadwick, F, McKay, A, Martinez-Martinez, A, Rees, N, Kraemer, T, Macgregor, S, Weller, A

“…[Rh(Cy2PCH2CH2PCy2)(–NBA)][BArF4] and the polymorphs of [Rh(Cy2PCH2CH2PCy2)(ethene)2][BArF4] are shown to be effective in Solid-state Molecular OrganoMetallic catalysis (SMOM–cat) for the isomerization of 1–butene to a mixture of cis– and trans–2–butene at 298 K and 1 atm, and studies suggest that catalysis is likely dominated by surface–active species. …”
