transformations is of interest for both academic and industrial research. Here, a benign palladium‐based catalyst system for the alkoxycarbonylation of conjugated dienes under acid‐free conditions has been developed. This atom‐efficient transformation provides straightforward access to a variety of β,γ‐unsaturated esters in good to excellent yields and often with high selectivities. As an industrially
The Pd(cod)Cl2-catalyzed alkoxycarbonylation of conjugateddienes to β,γ-unsaturated esters was approached by both intramolecular phosphinesulfonate L1 and intermolecular PPh3/PTSA in this study. However, the poor solubility of the Pd/L1 complex and the labile monodentate Pd/PPh3 structure restricts the system efficiency, especially for the scale-up application. By contrast, the stable and well-soluble
