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