Abstract The polystyrene-supported Pd(II) N , N -dimethylethylenediamine complex was prepared and characterized by various techniques, including Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), atomic absorption spectroscopy (AAS), and thermal analysis (TG-DTA). This heterogeneous Pd(II) catalyst works efficiently for the Suzuki–Miyaura

functionalization reactions in organic synthesis. Despite the seminal breakthrough of the Pd-catalyzed C(sp2)–H arylation of simple arenes via a concerted metalation–deprotonation (CMD) pathway in 2006, understanding the site-selectivity of the reaction still remains elusive. Here, we have comprehensively investigated the scope, site-selectivity, and mechanism of the Pd-catalyzed direct C–H arylation reaction of
