Efficient synthesis of 2,3-diarylbenzo[b]thiophene molecules through palladium (0) Suzuki–Miyaura cross-coupling reaction and their antithrombolyitc, biofilm inhibition, hemolytic potential and molecular docking studies. Zinc Enolate/Sulfinate Prepared from a Single-Run Reaction Using Zinc Dust with
Amine synthesis via iron-catalysed reductive coupling of nitroarenes with alkyl halides. However, Negishi and Suzuki couplings are better choices for large-scale operations.

A novel procedure for the preparation of zinc reagents: a practical synthesis of (+)-biotin. Negishi cross-coupling reaction catalyzed by an aliphatic, phosphine based pincer complex of palladium. Coordination to transition metals as sigma-acceptor ligands was found to enable the activation of fluoro silanes, opening the way to the first transition met-al-catalyzed Si-F bond activation. The Negishi cross coupling is a reliable synthetic method, which involves palladium or nickel-catalyzed coupling of organozinc reagents with various halo derivatives (e.g., aryl, vinyl, benzyl, or allyl) and has a broad scope to assemble diverse targets. A palladium catalyst composed of a new biaryldialkylphosphine ligand, CPhos, effectively promotes the rate of the reductive elimination step relative to the rate of the undesired β-hydride elimination.

A synthetic approach to palmerolides via Negishi cross coupling.
Negishi coupling has been applied in the synthesis of In a novel modification palladium is first oxidized by the Recent conditions for the Negishi reaction have demonstrated extremely broad scope and tolerance of a broad range of functional groups and heteroaromatic nuclei and proceed at or near room temperature.The Negishi coupling is not employed as frequently in industrial applications as its cousins the Where the Negishi coupling is rarely used in industrial chemistry, a result of the aforementioned water and oxygen sensitivity, it finds wide use in the field of The Stille coupling has been most widely applied in aryl and heteroaryl syntheses and it should be the method of choice for small-scale syntheses where toxicity is not a great concern.
