Heterogeneous Stille and Sonogashira cross-coupling reactions over palladium anchored mesoporous silica catalyst

A Pd-based heterogeneous catalyst (Pd(II)-MCM-41) derived from post-synthesis modification of mesoporous silica, MCM-41, has been successfully employed in catalytic Stille and Sonogashira cross-coupling reactions. The catalyst affords good yields in all cross-coupling reactions. Notably, the catalyst is capable of activating less reactive chlorobenzene with moderate yield in both the coupling r...

Cyclization-carbonylation-cyclization coupling reaction of propargyl ureas with palladium(II)-bisoxazoline catalyst.

The cyclization-carbonylation-cyclization coupling reaction (CCC-coupling reaction) of propargyl ureas catalyzed by Pd(II)(box) complexes afforded symmetrical ketones bearing two 2-amino-2-oxazoline groups in good to moderate yields.

Immobilized Palladium-pyridine Complex on γ-Fe2O3 Magnetic Nanoparticles as a New Magnetically Recyclable Heterogeneous Catalyst for Heck, Suzuki and Copper-free Sonogashira Reactions

A new immobilized palladium-pyridine complex on γ-Fe2O3 magnetic nanoparticles was synthesized and characterized by SEM, TEM, TGA, ICP, XPS, XRD, FT-IR and CHN analysis. The catalytic activity of synthesized catalyst has been investigated in Heck, Suzuki and Sonogashira coupling reactions using a series of aryl halides. The catalyst was easily isolated from the reaction mixture by an external m...

Mechanisms of double and single carbonylation reactions catalyzed by palladium complexes

Mechanisms of double carbonylation reactions catalyzed by palladium complexs to give a-keto amides and a-keto esters, stoichiometric double carbonylation of ally1 carbonates, and cyclization carbonylation . of 3-butenoic acid to give cyclic anhydrides are discussed as combination of elementary processes of organometallic reactions.
