In water it's better: In‐situ‐generated [Ru(O2CR)2(arene)] catalysts efficiently perform the direct ortho‐arylation of functional arenes with chloroarenes or chloroheterocycles in water (see scheme; KOPiv=potassium pivalate), without the need for a surfactant. The activity of these catalysts is higher in water than in organic solvents.

developed as a catalyst to effect aromatic C–H bondactivation and C–C coupling reactions in water. Cross-coupling reactions were performed in DI/distilled water under air- and ligand-free conditions without further activation of the catalyst. Synthesis of an advanced intermediate of CETP inhibitor, Anacetrapib, in water has been demonstrated to give a single regioisomer using the MCAT-53 catalyst.
