Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The thermal reactions of the heteronuclear oxide cluster [Ga₂MgO₄]^.+ with methane and water have been studied using state‐of‐the‐art gas‐phase experiments in conjunction with quantum‐chemical calculations. The significant reactivity differences, favoring activation of the strong OH bond, can be ascribed to a proton‐coupled electron transfer (PCET) mechanism operative in the activation of water. This study deepens our mechanistic understanding on how inert RH bonds are cleaved by metal oxides.</p> </abstract>
