A Highly Selective Catalyst for Partial Hydrogenation of 1,3‐Butadiene: MgO‐Supported Rhodium Clusters Selectively Poisoned with CO

A gateway to partial hydrogenation: Supported rhodium species with an essentially molecular character were precisely designed for the selective partial hydrogenation of 1,3-butadiene to give n-butenes, transforming a metal that is traditionally considered unselective into one that is highly selective.
