RT journal article T1 New achievements on C-C bond formation in water catalyzed by metal complexes A1 Scalambra, Franco A1 Lorenzo-Luis, Pablo A1 Ríos Hierro, Isaac de los A1 Romerosa, Antonio A2 Ciencia de los Materiales e Ingeniería Metalúrgica y Química Inorgánica K1 C–C coupling K1 C–C bond formation K1 Homogeneous catalysis K1 Catalysis in water K1 Water soluble metal complexes AB The C-C coupling is the best strategy to obtain new organic molecules and building blocks from economical and abundant small molecules. Traditionally these reactions are accomplished in organic solvents, which are often dried before use as water molecules can react quickly with both the catalyst or the intermediate of the reactions, blocking the catalytic cycle. Nevertheless, the efforts of the researchers are providing new synthetic procedures in water that can substitute some of those, previously developed, "dry reactions". In the last years, really useful processes to obtain C-C bonds in water were proposed. These reactions usually are catalysed with 4d-metals but also examples with metals of the first transition row were proposed. This review aims to summarize and order by types the C-C coupling catalytic reactions in water published during the last five years. The abundance of reactions and the significance of the published results shows that a long way is needed to achieve a good knowledge of catalytic C-C coupling reactions in water. Nevertheless, accomplish this objective can provide significant and valuable synthetic processes, more economical, cleaner, more selective, therefore friendlier and more respectful with nature.
