Chemistry of ruthenium with some dioxime ligands. Syntheses, structures and reactivities

Reaction of two dioxime ligands, viz. dimethylglyoxime (H2dmg) and diphenylglyoxime (H2dpg). (abbreviated in general as H2L. where H stands for the oxime protons) with [Ru(PPh3)3Cl2] in 1:1 mole ratio affords complexes of type [Ru{PPh3)2(H2L)Cl2]. Structure of the [Ru(PPh3)2(H2dpg)Cl2] complex has been solved by X-ray crystallography. The coordination sphere around ruthenium, is N2P2Cl2 with the two PPh3 ligands in frans and the two chlorides in cis positions. Reaction of the dioxime ligands with [Ru(PPh3)3Cl2] in 2:1 mole ratio in the presence of a base affords complexes of type [Ru(PPh3)2(HL)2]. Structure of the [Ru(PPh2(Hdmg)2] complex has been solved by X-ray crystallography. The coordination sphere around ruthenium is N4P2 with the two PPh3 ligands in trans positions. Reaction of the [Ru(PPh3)2H2dpg)Cl2 complex with a group of bidentate acidic ligands, viz. picolinic acid (Hpic), quinolin-8-ol (Hq) and 1-nitroso-2-naphthol (Hnn), (abbreviated in general as HL', where H stands for the acidic proton) in the presence of a base affords complexes of type [Ru(PPh3)2(H2dpg)(L')]+ isolated as perchlorate salts. All the complexes are diamagnetic (low-spin d6, S = 0) and in dichloromethane solution show several intense MLCT transitions in the visible region. Cyclic voltammetry on all the complexes shows a reversible ruthenium(II)-ruthenium(III) oxidation within 0.36-0.98 V versus SCE followed by a quasi-reversible ruthenium(III)-ruthenium(IV) oxidation within 0.94- 1.60 V versus SCE.

Interaction of Oximes with Dichlorotris(triphenylphosphine)-ruthenium(II)

Dichlorotris(triphenylphosphine)ruthenium(II), RuCl2(PPh3)3, has been treated with (a) chelating oximes (α-dioximes, α-carbonyloximes, α-imino-oximes, hydroxy-oximes, and pyridine oximes); and (b) simple oximes such as acetoxime, cyclohexanone oxime, etc., both without and with added base.Thirty new compounds with oximes as neutral ligands or as uninegative anions have been characterised by infrared (i.r.) and (1)H and (31)P nuclear magnetic resonance (n.m.r.) spectra.All the compounds contain bound triphenylphosphine groups.The interaction of RuCl2(PPh3)3 with hydroxilamine in the presence of NaOH gives a compound RuCl(NH2O)(NH2OH)(PPh3)2, which is considered to have an η2-hydroxylaminato-group.
