Design Strategy of Metal Nanoparticle Catalysis for C−H Bond Activation Reactions

Supported metal nanoparticles have attracted growing research interest as promising sustainable catalysts. This Concept article will describe recent studies that explored the novel catalytic functions and designing methods of metal nanoparticles for C−H bond activation reactions. Examples include oxidative homocoupling of arenes, dehydrogenative alkylation of benzenes, selective H/D exchange reactions, and α,β-dehydrogenation of ketones.

Abstract

C−H bond activation reactions facilitate highly efficient molecular transformations without requiring pre-activating substrates. While the majority of reported reaction systems for C−H activation rely on metal complexes, certain reactions have demonstrated unique or superior catalysis of metal nanoparticles. This Concept article seeks to delineate recent reports that examine the novel catalysis and design strategy of supported metal nanoparticles for C−H bond activation reactions. These reactions include oxidative homocoupling of arenes, dehydrogenative alkylation of benzenes, selective H/D exchange reactions, and α,β-dehydrogenation of ketones.
