Some reactions of phosphine complexes of platinum(0) and palladium(0) with acidic solvents; a phosphorus-31 nuclear magnetic resonance study

Abstract

The complexes [Pt(PPh3)4] and [Pt(PPh3)3] react quantitatively with anhydrous hydrogen chloride and bromide to give cis-dihalogenobis(triphenylphosphine)platinum(II) complexes and hydrogen. [Pd(PPh3)4] In liquid hydrogen chloride reacts to give trans-dichlorobis(triphenylphosphine)palladium(II) and hydrogen but the reaction proceeds with further replacement of triphenylphosphine at the metal, since trans-[PdCl2(PPh3)2] itself reacts in liquid hydrogen chloride to give triphenylphosphonium tetrachlorodi-µ-chloro-dipalladate(II), [Ph3PH]2[Pd2Cl6]. [NiCl2(PPh3)2] Reacts with liquid hydrogen chloride to give NiCl2 and Ph3PH + HCl2. The reactions of [Pt-(PPh3)4] with sulphuric and trifluoroacetic acids have also been studied.
