Summary: Aryl fluorosulfates are versatile building blocks in organic synthesis and have gained increasing attention in SuFEx click chemistry. They can be easily prepared from phenols using low-cost sulfuryl fluoride as a sulfonyl fluoride provider. They have been used as less toxic and more atom economical alternatives to triflates in numerous cross-coupling reactions. This review summarizes the recent advances and developments in utilizing aryl fluorosulfates as electrophilic partners in cross-coupling reactions.

Summary: This study presents a pioneering example of nickel-catalysed enantioconvergent Stille cross-coupling reactions. The reactions result in the formation of C-C bonds in good to high yields with excellent stereoselectivity, providing a practical and cost-effective method for synthesis. The innovative use of synergistic photoredox/nickel catalysis enables a novel single-electron transmetalation process, opening up new research possibilities in the field of Stille reactions.

Summary: An eco-friendly approach was used to generate Ni nanoparticles on a magnetized cellulose biopolymer, resulting in a core-shell type nanocomposite (Fe3O4@CNF@Ni). The nanocomposite was characterized using various advanced techniques and its catalytic performance was evaluated in the synthesis of biaryl derivatives. The results showed that the nanocomposite exhibited high stability and catalytic efficiency.

Summary: In this paper, a group of copper-based ternary deep eutectic solvents (Cu-DESs) were synthesized and applied in Glaser-type homo- and cross-coupling of terminal alkynes. These reactions occurred under exogenous-ligand-free, base-free, and additive-free conditions, providing satisfactory to excellent yields (up to 99%) under mild conditions. The Cu-DESs can be recycled eight times, with water being the only by-product, complying fully with the principles of green chemistry.

Summary: A novel Pd(II)-polymeric pre-catalyst was successfully prepared and demonstrated good activity in the Suzuki-Miyaura coupling reaction. The catalyst showed recyclability and its performance was affected by the concentration of the cross-coupling partners. The presence of oxygen was found to be crucial in preventing the formation of inactive Pd(0) aggregates.

Summary: Carbon-fluorine bonds are stable but can be selectively transformed under appropriate conditions, making them useful synthetic methods in organic chemistry. This review focuses on C-C bond formation at monofluorinated sp(3)-hybridized carbons via C-F bond cleavage, including cross-coupling and multi-component coupling reactions. The mechanisms of C-F bond cleavage on sp(3)-hybridized carbon centers are categorized into three types: Lewis acids promoted F atom elimination, nucleophilic substitution with metal or carbon nucleophiles, and cleavage of C-F bonds via single electron transfer. Furthermore, the unique characteristics of alkyl fluorides compared to other (pseudo)halides as electrophilic coupling counterparts are discussed.

Summary: The Sonogashira reaction is a key cross-coupling reaction in organic synthesis, forming a C-C bond between a vinyl or aryl halide and a terminal alkyne. While traditionally requiring copper and phosphines or amines as co-catalysts and bases, recent developments have enabled the reaction to proceed without these components. This advancement could promote the principles of green chemistry and enhance the economic feasibility of the reaction.

Summary: This study reports the design, synthesis, and application of naturally occurring cellulose from agro waste pomegranate peel as a novel support for active biogenic Pd nanoparticles for Suzuki-Miyaura and Sonogashira cross-coupling reactions at room temperature. The cellulose matrix enables well dispersion of Pd nanoparticles over the support to generate Pd@cellulose, exhibiting excellent catalytic activity and recyclability under ligand-free mild reaction conditions. The synthesized cellulose nanofibers and Pd-anchored heterogeneous nanofibers were characterized through various analytical techniques.

Summary: Carbon-carbon cross coupling reactions are important organic transformations, and various catalysts have been developed for these reactions. Phosphine-based ligands were initially used but were toxic and sensitive. Schiff base ligands, synthesized from condensation reactions, are stable and widely utilized in C-C cross coupling reactions. Palladium complexes are well-known catalysts, but other transition metal complexes are also of interest. This review focuses on the synthesis of Schiff base ligands, their complexation especially with Pd, Co, and Cu, and their application in C-C cross coupling reactions.
