Synthesis and Structural Characterization of an Authentic Platinum(IV) Carbonyl Compound

Abstract

The oxidative addition of Br2 to [NBu4]2[Pt(C6F5)4] followed by halide extraction with AgClO4 in the presence of CO gave [NBu4][trans-PtIV(C6F5)4Br(CO)], the first Pt(IV) carbonyl derivative to be structurally characterized. It is demonstrated that the previously reported [NEt4][PtBr3H2(CO)] complex is, in fact, the Pt(II) derivative [NEt4][PtBr3(CO)].
