• Ruthenium complexes
• Aerobic oxidation
• Polyoxometalates
• Homogenous catalysis

A novel ionic compound (3, [RuCl4(L)(2)](3)PW12O40) containing the Ru(III)-complex cation and alpha-Keggin-type phosphotungstate anion was synthesized and proven to be the efficient catalyst for aerobic oxidations of alcohols free of base and nitroxyl radical. Specially, 3 could be reused at least five runs without obvious activity loss. The stability of 3 was dramatically improved due to the incorporation of [PW12O40](3-) as the counter-anions, leading to its available recyclability.
