Synthesis of Platinum Dirhenium Dodecacarbonyl and Its Use as a Catalyst Precursor (Bimetallic, Rhenium, Heterogeneous)

The use of a mixed-metal compound as a precursor to oxide-supported bimetallic catalysts offers the potential to control the composition of the resulting bimetallic particles. The reaction of HM(CO)(,5) (M = Re,Mn) with Me(,2)Pt(COD) (COD = 1,5-cyclooctadiene) in the presence of CO leads to the formation of the heterobimetallic compounds Re(,2)Pt(CO)(,12) and Mn(,2)Pt(CO)(,12) in high yield. HM(CO)(,5) can be readily prepared and isolated in (TURN)85% yield by the reaction of M(CO)(,5)Br with Zn dust and H(,3)PO(,4) in tetraglyme, followed by vacuum distillation. A single-crystal x-ray diffraction analysis of Re(,2)Pt(CO)(,12) shows that the molecule ideally possesses D(,2h) symmetry with octahedral coordination about each rhenium atom and square planar (trans) geometry about the platinum atom.
