Cover Feature: Durable Heterogeneous Pd-PNP Pincer Complex for CarbonCarbon Bond Formation in Continuous-Flow Systems (ChemSusChem 19/2025)

Abstract

The Cover Feature shows how, within a polymer pore reminiscent of swollen Merrifield resin, a continuous stream traverses a landscape of PNP-pincer sites that immobilize palladium species. During a robust Mizoroki–Heck transformation under flow conditions, the catalyst is confined to the resin microenvironment to suppress leaching and sustain extended operation. The tunnel-like perspective conveys mass transport through the fixed bed, while the overall silhouette subtly alludes to “SCORPI”, evoking the form of a scorpion.
