Designing a heterogeneous Pd(ii)–NHC-based C–H activation catalyst on a self-supported coordination polymer platform

Abstract

In this work, we report a single-site, heterogeneous Pd(II)–NHC-based oxidative C–H activation catalyst, designed on a self-supported coordination polymer platform. The system has been applied successfully for selective arene C–H monohalogenation reactions affording a good degree of efficiency and reusability. Control experiments suggested that the Ru(II)–terpyridine-based coordination network scaffolding the covalently attached Pd(II)–NHC catalytic centres was highly robust under oxidizing conditions and rendered superior activity than the homogeneous counterpart.
