New Homogeneous And Robust Catalyst for Heck and Suzuki Reactions
In this work, different ethyl 2,4-dioxo-4-arylbutanoate derivatives were prepared and evaluated for their Src Kinase inhibitory activity. For this purpose, the appropriate substituted acetophenone derivatives reacted with diethyl oxalate in the presence of sodium ethoxide in dried ethanol to give the corresponding products. All compounds showed moderate activities comparing with staurosporine a...
متن کاملNew Homogeneous And Robust Catalyst for Heck and Suzuki Reactions
A novel and efficient palladium-based homogeneous catalyst was fabricated and used as a robust catalyst in Suzuki–Miyaura cross-coupling and Heck reactions. 2-Amino-N(pyridin-2-ylmethyl)benzamide was introduced as a versatile ligand for palladiumcatalyzed cross-coupling reactions. The desired active and stable homogeneous Pd catalyst was prepared via the coordination of Pd with 2-amino-N-(pyrid...

متن کاملImmobilized 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...
متن کاملSynthesis of novel tridentate ligand-based palladium catalyst and investigation of its reactivity towards Suzuki, Sonogashira and Heck coupling reactions
We have demonstrated a simple and efficient route for the synthesis of a novel imine based tridentate ligand and its Pd-complex to investigate the C-C cross-coupling reactions, that involve column chromatography purification in only one step. The catalytic activity of the newly synthesized catalyst was studied for the Suzuki, Sonogashira and, Heck cross-coupling reactions under mild conditions....
