Summary, etc. A new water-soluble rhodium(III) complex [Rh(<em>η</em><sup>4</sup>-<strong>L</strong>)Cl] (<strong>1a</strong>) was synthesized by reacting RhCl<sub>3</sub>.3H<sub>2</sub>O with Salophen ligand  [<strong>L</strong> = N,N<strong><sup>′</sup></strong>-bis(salicylidene)-1,2-phenylenediamine (<strong>a</strong>)] in 1:1 molar ratio in dichloromethane solution. The complex <strong>1a </strong>was characterized by FT-IR, UV-Vis, ESI-MS, <sup>1</sup>H and <sup>13</sup>C NMR spectroscopy. Theoretical calculations (B3LYP) and spectroscopic evidence recommends that the ligand <strong>a</strong> coordinates to the Rh centre through imine N and phenolic O donor atoms.<strong> </strong>The complex <strong>1a</strong> emerged out to be an effective catalyst for oxidation of alcohols in water. <sub> </sub>Magnificent yields of carbonyl compounds are acquired for a comprehensive assortment of substrates with H<sub>2</sub>O<sub>2</sub> as oxidant at a relatively low loading of catalyst. Thus, the Rh(III)-H<sub>2</sub>O-H<sub>2</sub>O<sub>2</sub> catalytic system could act as an environmentally benign alternative to oxidation methods in conventional organic solvents.
