Pd Functionalized MCM-41 Catalysts for Suzuki Reactions

Palladium (II) containing siliceous-MCM-41 has been prepared according to an original pathway by the reaction between silica precursors (imeo) and MCM-41. The resulting materials have been characterized by chemical analysis, X-ray powder diffraction, nitrogen sorption isotherms, and SEM and catalysis tests. Catalysis tests show that the very dispersive structure of the Pd-MCM-41 promotes the generation of fairly active catalysts for Suzuki cross-coupling of aryl chlorides and phenyl boronic acid under specific conditions, where the leaching of redox-active species has been minimized (less than 2 ppm).
