Mechanochemistry through Extrusion: Opportunities for Nanomaterials Design and Catalysis in the Continuous Mode. Trentin, Oscar Polidoro, Daniele Perosa, Alvise Rodríguez-Castellón, Enrique Rodríguez-Padrón, Daily Selva, Maurizio Metales - Extrusión Materiales nanoestructurados Mecanoquímica The potentialities of mechanochemistry trough extrusion have been investigated for the design of nanosized catalysts and their use in C-C bond-forming reactions. The mechanochemical approach proved successful for the synthesis of supported palladium nanoparticles with mean diameter within 6–10 nm, achieved by the reduction of Pd(II) acetate with ethylene glycol, in the absence of any solvent. A mesoporous N-doped carbon derived from chitin as a renewable biopolymer, was used as a support. Thereafter, the resulting nanomaterials were tested as catalysts to implement a second extrusion based-protocol for the Suzuki-Miyaura cross-coupling reaction of iodobenzene and phenylboronic acid. The conversion and the selectivity of the reaction were 81% and >99%, respectively, with a productivity of the desired derivative, biphenyl, of 41 mmol gcat gcat-1 h-1. 2024-05-31T10:49:48Z 2024-05-31T10:49:48Z 2024-05-31T10:49:48Z 2023-08-08 journal article Trentin, O., Polidoro, D., Perosa, A., Rodríguez-Castellon, E., Rodríguez-Padrón, D., & Selva, M.
