Abstract

The reaction of Pt(COD)2 with one equivalents of IBut and PBut3 at room temperature yields the unsaturated platinum mixed N-heterocyclic carbene and phosphine complex Pt(IBut)(PBut3), 1. Complex 1 reacts rapidly with O2 and CO to form the dioxygen adduct Pt(IBut)(PBut3)(η2-O2), 2 and Pt3 trimer cluster complex [Pt(IBut)(CO)]3, 3, respectively. Complex 2 further reacts with CO2 at room temperature to give the peroxycarbonate complex Pt(IBut)(PBut3)[η2-OOC(O)O], 4, and the first example characterized by single crystal X-ray diffraction. The reaction of complex 2 with acetone also resulted in the formation of the peroxoacetonate complex Pt(IBut)(PBut3)[η2-OOC(CH3)2O], 5. All the structures for the complexes 1–5 were characterized by X-ray crystallographic studies.
