New achievements on C-C bond formation in water catalyzed by metal complexes

Ligand Modifications on a Cp(quinolate)Ru Catalyst to Improve Its Stability in a Bio-orthogonal Deprotection Reaction

“…Recently, numerous new achievements concerning the research of metal-catalyzed reactions in water were obtained. For instance, the synthesis of carbonyl compounds by isomerization of alcohols and the formation of C–C bonds through metal-catalyzed coupling reactions are now possible in aqueous media. Metal-catalyzed carbene transfer reactions also proved to be applicable in biologically relevant conditions, expanding the range of possible bio-orthogonal reactions .…”

Novel cyano-activated Cu(ii) complexes of arylhydrazones of active methylene nitriles and their catalytic application for azide–alkyne cycloaddition in water and glycerol

“…In recent years, there has been growing interest in the use of water as a solvent for catalytic reactions due to its abundance, low cost, and environmentally friendly properties. [11][12][13] In some cases, catalytic conversions are often better in an aqueous medium than in pure organic solvents due to the unique features of water such as high dielectric constant, the ability to act as a nucleophile or a leaving group, and the ability to solubilize polar reactants and catalysts. [14][15][16][17][18] Although homogeneous CuAAC can proceed in aqueous medium, the presence of an organic co-solvent (e.g.…”

Direct Michael addition/decarboxylation reaction catalyzed by a composite of copper ferrite nanoparticles immobilized on microcrystalline cellulose: an eco-friendly approach for constructing 3,4-dihydrocoumarin frameworks

“…Metallic and bimetallic nanoparticles are the most interesting catalysts for C-C bond formation due to having robust qualities especially such as a higher surface area with stability and easy separation. 29 These qualities make them appropriate for various applications with a wide range of catalysis. 30 However, during the application of metal oxide nanoparticles, some drawbacks are faced like leaching and recovery.…”
