ResumoThe synthesis and characterization of (p-cymene)RuII, Cp*RhIII and Cp*IrIII complexes with N-alkyl and N-aryl substituted 3-hydroxy-2-methyl-4-pyridone ligands is reported. All compounds display an unusually high solubility in water. With the chiral ligand N-(o-C6H4CO2Me)-3-hydroxy-2-methyl-4-pyridone two isomers were obtained but no diastereoselectivity was observed. The structure of [(p-cymene)Ru(C9H12NO2)Cl] (2) was determined by single crystal X-ray diffraction. Reactions of [(p-cymene)Ru(C7H8NO2)Cl] (1) with n-butylamine and triphenylphosphine were shown to result in substitution of the chloride ligand.
