Ligand displacement reactions performed in polar solvents afford a convenient general route to an extensive series of cationic complexes containing dialkyl phenylphosphonite, P(OR)2Ph, and alkyl diphenylphosphinite, P(OR)Ph2, ligands (R = Me, Et) which may be isolated as their tetraphenylborate salts. These products were characterized by elemental analysis, proton nmr spectroscopy, and conductivity measurements. Complex cations isolated and characterized in this manner include the hydrides [RuHL′5]+ and [IrHL′5]2+, the dinuclear species [L3RuX3RuL3]+, and the mononuclear cations [RuL′6]2+, [IrL′5]+, [IrL4]+, [PdL4]2+, [PtL4]2+, [CuL4]+, [AgL4]+, and [AuL4]+ [L′ = P(OMe)2Ph; L = P(OR)2Ph, P(OR)Ph2; R = Me, Et; X = Cl, Br]. Qualitative descriptions of the coupling patterns observed in the nmr spectra of the complex cations are given and are interpreted in terms of ligand dissociation and rearrangement processes.
