Kinetic Aspects of Suzuki Cross-Coupling Using Ligandless Pd Nanoparticles Embedded in Aromatic Polymeric Matrix

During the last decades, palladium nanoparticles (Pd(0) NPs) and Pd(II) compounds were shown to be attractive catalysts for fine organic synthesis. Nanostructured Pd(0) or have a relatively low environmental impact, but, at same time, they are indispensable such processes as Suzuki cross-coupling. This paper describes preparation of supported/embedded in hyper-cross-linked polystyrene (HPS) compares their activity cross-coupling between phenylboronic acid 4-bromoanisole. Obviously, charge ↔ Pd(II)) changes continuously during reaction catalytic cycle. It would seem that use starting form should not affect reaction’s kinetic laws both catalysts, but special individuality is manifested them. Nanoparticulate stable reaction. In contrast, based on extremely active initial period reaction, then “hot form” catalyst rapidly converted into Pd(0), whose identical preliminarily reduced catalyst. work discusses possible nature this phenomenon. A mathematical model was suggested able adequately describe experimental data. The level reliability (R2) correlation calculated data R2 = 0.97–0.99.
