Abstract

Abstract : An extended Ru II (terpy)2 -based coordination polymer provides a potential scaffold to design a self-supported, single-site Pd II (NHC) oxidative catalyst for challenging reactions such as selective arene monohalogenation with enhanced catalytic activity compared to the homogeneous counterpart. 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.
