Direct ligand reactions of functionalised σ-aryl groups coordinated to ruthenium (II) have been developed. The reduction of a σ-nitrophenyl ligand to a σ-aminophenyl ligand and subsequent acetylation to form a series of σ-amidophenyl containing complexes is discussed. An alternative route to σ-aminophenyl complexes which uses a mercury transmetallation reagent is also reported. The complexes Ru(C6H4NO2-4)Cl(CO)(PPh3) 2 (1), Ru(C6H4NO2-4)(η2-S 2CN[CH3]2)(CO)(PPh3)2 (2), Ru(C6H4NH2-4)Cl(CO)(dmf)(PPh3) 2 (3), Ru(C6H4NH2-4)(η2-S 2CN[CH3]2)(CO)(PPh3)2 (4), Ru(C6H4NH2-4)(η2-O 2CCH3)(CO)(PPh3)2 (5), Ru(C6H4NHC[O]CH3-4)-(η2-S 2CN[CH3]2)(CO)(PPh3)2 (6), Ru(C6H4NHC[O]C6H4-4)(η 2-S2CN[CH3]2)(CO)(PPh 3)2 (7), 2,6-{Ru(C6H4NHC[O]-4)-(η2-S2CN [CH3]2)(CO)(PPh3)2} 2C5H3N (8) and Ru (C6H4NHC[O]CH3-4)(η2-O 2CCH3)(CO)(PPh3)2 (9) have been prepared and characterised using IR and 1H NMR spectroscopy. The crystal structures of 5 and 9 have been determined by X-ray diffraction methods. Crystal data: 5, C45H39NO3P2Ru·H2O, a = 9.955(2), b = 11.607(3), c = 19.175(7) A, α = 75.78(3), β = 85.17(2), γ = 65.06(3)°, triclinic, space group P1, Z = 2; 9, C47H41NO4P2Ru, a = 9.752(1), b = 11.398(6), c = 19.447(3) A, α = 83.24(2), β = 86.40(1), γ = 68.19(3)°, triclinic, space group P1;, Z = 2.
