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

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.
