Disclosed is a method for treating water, including the extraction of at least two ionic species, the ionic species including an anionic species and a cationic species and being present in the water to be treated, the method especially including a step of mixing a liquid hydrophobic organic phase and the water to be treated, the water to be treated being in the liquid state, in order to subsequently obtain liquid treated water and a hydrophobic liquid organic phase loaded with the ionic species, and a step of thermal regeneration of the organic phase loaded with chemical species. Also disclosed are compounds and compositions that can be used in the method.

An alternative approach to formation of a C-C bond at a meta-position of an aromatic compound is disclosed that employs an ethylenically unsaturated bicyclic compound as a transient mediator to achieve meta-selective C-H activation with a simple and common ortho-directing group. The use of a pyridine-based ligand assists in relaying the palladium catalyst to the meta-position by the unsaturated bicyclic compound following initial ortho-C-H activation.
