Structural characterization of the product of intramolecular oxygen transfer from a ketone to CO within the coordination sphere of a Zr-Fe heterodimetallic complex

The Zr-Fe complex: [HC{SiMe2N(2,3,4-F3C6H2)}(3)Zr-FeCp(CO)(2)] (1) reacts with 1,2-diphenylcyclopropenone to give [HC{SiMe2N(2,3,4-F3C6H2) }(3)Zr(mu -CO2)FeCp(CO)(C3Ph2)] (2). A single-crystal X-ray structure analysis has now established the molecular structure of the product of oxygen transfer of the cyclopropenone to a carbonyl ligand. The chiral Fe center in, complex: 2 bears a carbonyl, a cyclopropenylidene ligand, and the C atom of a mu (2)-eta (3)-bridging CO2 ligand.
