A palladium-based catalyst supported on DABCO-functionalized silica was successfully prepared by a facile procedure. The prepared heterogeneous catalyst showed a high activity for the Suzuki-Miyaura reaction of aryl bromides, affording excellent yield in all the cases investigated. Interestingly, the catalyst could be quantitatively recovered from the reaction mixture and recycled for five times without any significant loss in activity. Furthermore, this protocol could be extended to the palladium catalyzed synthesis of annulated pyrazines. Springer Science+Business Media, LLC 2012.

A simple, efficient and ligand-free protocol for the Suzuki-Miyaura reaction and base-free Heck-Matsuda reactions under mild reaction conditions have been developed over palladium supported on activated carbon (Pd/C) in an aqueous hydrotropic solution. The catalyst Pd/C was fully characterized by TG-DTA, SEM, EDS, XRD, XPS, BET and ICP-AES analyses. This green methodology represents a cost-effective and operationally convenient method for the synthesis of a variety of biaryls, prochiral ketones, and acrylates under the conditions that are tolerant for a broad range of functional groups with good to excellent yields. The developed Pd/C-aqueous hydrotrope combined catalytic system is well suited for the 3R approach (reducible, robust, and recyclable) for different cross-coupling reactions without an appreciable loss of its activity.
Palladium supported hybrid cellulose-aluminum oxide composite for Suzuki-Miyaura cross coupling reaction

A cellulose-aluminum oxide composite was prepared and modified with organo-functional groups by reacting with the coupling reagent (CH 3O)3Si(CH2)3NH2 through Al-O-Si bonds. The amino groups confined in the composite were found to be efficient for palladium entrapment, leading to a highly active and reusable heterogeneous catalyst (Pd@Al2O3-CELL) for Suzuki-Miyaura cross coupling reaction in water and H2O/DMF (8:2) mixture at 80 °C.
