Pd-Nanoparticles-Catalyzed C(sp2)–H Arylation for the Synthesis of Functionalized Heterocycles: Recent Progress and Prospects.

This article provides an overview of the recent progress and prospects of using palladium nanoparticles (Pd NPs) as catalysts for the synthesis of functionalized heterocycles through C(sp2)-H arylation. Heterocycles are important in various fields, including pharmaceuticals and materials science. Traditional synthetic approaches have limitations, but transition-metal-catalyzed C-H activation offers a more efficient alternative. Heterogeneous catalytic approaches using Pd NPs show promise in terms of catalyst recoverability and reusability. The article discusses different methods and catalysts for the synthesis of functionalized heterocycles, highlighting their advantages and potential applications. [Extracted from the article]
