Summary: In this study, the first Pd-catalyzed aryl-alkyl cross-coupling of alkylzirconocenes and aryl halides was reported, with the critical role of a commercially available N-heterocyclic carbene (IPr) ligand for the palladium catalyst. This mild protocol tolerates various functional groups and heterocycles and is applicable to both terminal and internal alkenes.

Summary: A recyclable nanomagnetic catalyst PAMAM G(0)-Pd@gamma-Fe2O3 is reported for catalytic C-C cross-coupling reactions of challenging substrates. The catalyst exhibits good solubility and catalytic activity for a variety of aryl chloride substrates under mild reaction conditions in aqueous media. The immobilization of the catalyst on a magnetic platform allows for effective recovery and reuse.

Summary: In recent years, Pd-catalyzed cross-coupling reactions have been widely used in various fields of chemistry. However, traditional phosphine ligands used in these reactions have limitations. Therefore, phosphine-free ligands and mixed donor P, N-ligands have attracted attention for their advantages in catalysis.

Summary: Carbon-carbon coupling reactions are of great interest for various applications. The use of greener solvents and heterogeneous metal catalysts is desirable. This study successfully synthesized biaryl compounds in water using carbon-supported Pd nanoparticles, achieving shorter reaction time. The utilization of TOP or TPP ligands slowed down Pd leaching. Additionally, a treatment with H2O2 was beneficial for improving the hydrophilicity of the carbon support. These results and methodology contribute to a greener future for C-C coupling reactions.

Summary: A copper-catalyzed sulfinyl cross-coupling reaction of sulfinamides with aldehyde-derived N-tosylhydrazones is reported. This approach provides an efficient and novel way to construct structurally diverse sulfoxides, with broad substrate scope and compatibility with various functional groups and pharmacophores. Moreover, the reaction can be scaled up to gram scale and carried out in a one-pot fashion directly from aldehydes.

Summary: Heteroaromatic sulfinates are effective nucleophilic reagents in Pd-0-catalyzed cross-coupling reactions with aryl halides. Base-activated, latent sulfinate reagents, such as beta-nitrile and beta-ester sulfones, have been introduced to address challenges in purifying and solubilizing metal sulfinate salts, as well as their tolerance to multi-step transformations. These latent sulfinate reagents have proven to be stable through multi-step substrate elaboration and amenable to scale-up processes.

Summary: The efficient Suzuki-Miyaura cross-coupling of ortho-fluoro aromatic secondary amides with aryl boronates is achieved using (KOBu)-Bu-t as an essential reactant. The base serves to extract a proton from the amide nitrogen, generating a weak conjugate base that acts as a directing group. The reaction demonstrates good tolerance for functional groups and a broad scope for aromatic amides, even at 60 degrees C.

Summary: This paper presents the first examples of palladium-catalyzed desulfinative cross-coupling reaction of polyhalogenated aryl triflates with aryl sulfinate salts. The catalyst system exhibited excellent reactivity and chemoselectivity in this reaction, which had a wide substrate scope and provided a simple method for constructing functionalized biaryl motifs. The interaction between the indolyl phosphine ligand and the Pd center played a key role in the reactivity and chemoselectivity of this reaction.

Summary: This study introduces a Ni/photoredox-catalyzed enantioselective reductive coupling of styrene oxides and aryl iodides, yielding enantioenriched 2,2-diarylalcohols. Analysis shows that enantioselectivity is correlated with the electronic properties of the ligands, with more electron-donating ligands leading to higher ee values. Experimental and computational studies support the hypothesis that reductive elimination is enantiodetermining and ligand electronic properties affect enantioselectivity by altering the position of the transition state structure.

Summary: Various methods have been investigated recently for the arylation of weakly acidic C(sp(3))-H bonds, with this study focusing on a base-mediated approach using organometallic superbases. The study developed conditions for high selectivity metalation using either n-BuLi/diamine or n-BuLi/KOtBu superbases, allowing for direct use in cross-coupling or formation of organozincs for reactions with functional groupdense organohalides.

Summary: The reactivity of carbonyl-tethered alkylidenecyclopropanes (ACPs) can be directed towards tandem cycloisomerization/cross-coupling processes by using Pd-0 catalysts with phosphorus-based monodentate ligands. This allows for the synthesis of a wide variety of highly functionalized cyclic alcohols and amines through the formation of key pi-allyl oxapalladacyclic intermediates which are trapped with external nucleophilic partners.
