Synthesis of fluorene-based oligomeric organoboron reagents via Kumada, Heck, and Stille cross-coupling reactions.
Boronic pinacol ester group is not reactive in Kumada, Heck and Stille coupling reaction conditions. Fluorene-based sophisticated organoboron compounds were synthesized by means of Palladium catalyzed Kumada, Heck and Stille cross-coupling reactions from halofluorenyl boronic esters.
متن کاملApplication of dimeric and monomeric ortho-palladated complexes as an efficient catalysts for Heck cross-coupling reaction
The catalytic acvtivity of dimeric and monomeric ortho-palladated complexes [Pd{C6H2(CH2NH2-(OMe)2,3,4}(µ-Cl)]2)2) and [Pd{C6H2(CH2NH2-(OMe)2,3,4}Cl(PPh3)](3), was investigated in Heck cross-coupling reaction. These complexes are more active and efficient catalysts for Heck cross-coupling reaction. The palladium complexes 2 and 3 is employed in the Heck cross-coupling reaction between styrene a...
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....
متن کاملSynthesis, Characterization and Catalytic Activity of Ligand Stabilized Palladium Nanoparticle: A Catalyst Compliment to the Heck Coupling Reaction
The palladium metal is the most frequently used metal because of its excellent catalytic efficiency and most flexible varying oxidation state. So, we report that palladium nanoparticles (Pd NPs) stabilized by a ligand (o-vanilindiphenylethanedionedihydrazone, L) using reverse micelles method have been synthesized, while all particles are in spherical shape and ranging between 10 and...
متن کاملPolystyrene Supported [N-(Alanine) Sulfonamide]/Palladium Chloride: Synthesis, Characterization, for Heck Coupling Reactions
Abstract As a monomer, the [N-(alanine)] para-styrene sulfonamide (ASS) was prepared, from the reaction of para-styrene sulfonyl chloride and (S)-(+)-alanine in the presence of KOH 1M as a base, and CH3Cl was used as solvent. The monomer confirmed using FT-IR and 1H-NMR spectroscopy. Polystyrene [N-(alanine) sulfonamide] (PASS) was also prepared from the polymerization of [N-(alanine)] pa...
