Preparation, characterization, and some reactions of tri-tert-butylarsine complexes of platinum(II) and palladium(II) chlorides

Article abstract of DOI:10.1021/ic50225a006

As(t-Bu)₃ reacts with platinum(II) chlorides to afford either trans-PtCl₂[As(t-Bu)₃]₂ or the dinuclear complex Pt₂(μ-Cl)₂Cl₂[As(t-Bu)₃] ₂. With palladium(II) chloride, however, only the dinuclear complex Pd₂(μ-Cl)₂Cl₂[As(t-Bu)₃] ₂ is formed even in the presence of excess As(t-Bu)₃. These complexes undergo substitution and/or bridge-cleavage reactions with CO, py, AsPh₃, Cl^-, or tertiary phosphines.
