Sažetak
Palladium-catalyzed cross-coupling reactions of aryl halides with various functionalization reagents are one of the most widely used methods for the preparation of diverse organic compounds, pharmaceuticals, and advanced materials. Although cyclopalladated complexes (palladacycles) are widely used as catalysts, the investigations into catalytic properties of doubly palladated compounds are almost non-existent. Recently, solid-state preparative methods have provided faster and environmentally-friendly access to palladacycles compared with time-consuming protocols usually performed in harmful solvents. Furthermore, the mechanochemical protocols for crosscoupling reactions can significantly shorten the reaction times and provide access to a wide array of new products that are sometimes unattainable in solution. In this work, we developed a mechanochemical procedure for the synthesis of new dicyclopalladated azobenzene compounds via ligand-directed C-H bond activation promoted by selected organic acids. In situ Raman monitoring of these reactions provided direct insight into the dynamics of the formation of complexes, while NMR and IR spectroscopy were used for the characterization of obtained products. A model Suzuki-Miyaura cross-coupling reaction between 4-bromoazobenzene and phenylboronic acid was carried out under mechanochemical conditions to compare the catalytic potential of prepared palladacycles of azobenzene.
