Since the rearrangement of metal-carbene-hydride complexes to metal-alkyl complexes is a facile and well-studied process, it seemed likely that a zirconoxycarbene-meal complex might be further reduced if a hydride were present on the same metal as the carbene ligand. In an effort to prepare such a complex, the authors have studied the reaction of the /eta//sup 2/-acylzirconium compounds Cp/sub 2/Zr(/eta//sup 2/-COR)Cl (3, R = CH/sub 3/; 4, R = CH/sub 2/CH/sub 2/CMe/sub 3/) with the rhenium hydride anion K/sup +/Cp(CO)/sub 2/ReH/sup /minus// 5. It appeared plausible that formation of a Re-Zr bond in intermediate B might occur and that acyl migration from zirconium to rhenium might ensue to produce intermediate C which possess the desired zirconoxycarbene and hydride ligands on rhenium. They report the reaction of /eta//sup 2/Cp(CO)/sub 2/ReH/sup /minus// 5 leads not only to the reduction of the acyl ligand but also to formation of mononuclear rhenium-carbene complexes Cp(CO)/sub 2/Re/double bond/CHR (8, R = CH/sub 3/, 9, R = CH/sub 2/CH/sub 2/CMe/sub 3/).
