: Nowadays palladium-catalyzed C–H bond activation is a useful approach for the synthetic transformation of organic compounds due to step economy, the use of non-prefunctionalized substrates and reduced chemical wastes. Among the various synthetic strategies, palladium catalyzed intra and inter-molecular C–H bond activation has recently drawn a lot of interest to synthesize the decorated π-conjugated polycyclic aromatic hydrocarbon. In this review, we have focused on recent progress along with previous strategies to synthesize various polynuclear aromatic hydrocarbons (PAHs) by the use of Pd-catalyzed C–H bond activation. We have also discussed the mechanistic details of the reaction intra and inter-molecular C–H bond activation.
