    Dynamic binuclear enediolato- and catecholato-zirconocene complexes relevant to the structural problem associated with sharpless oxidation catalysts
    摘要:
    Dimethylzirconocene complexes [ZrMe2(C5H4R)2](R = H or CH3) were treated with catechol to give the (catecholato)zirconocene complexes. Low-temperature NMR spectra indicated dimeric metallatricyclic structures for these complexes and the corresponding (ethene-1,2-diolato)- and (but-2-ene-2,3-diolato)-zirconocenes. Dynamic temperature-dependent NMR spectroscopy revealed that all these complexes underwent a thermally induced degenerate rearrangement process, similar to the reorganization reaction of some Sharpless catalyst precursors, with Gibbs activation energies close to 50 kJ mol-1. A labelling experiment showed the intramolecular nature of this automerization. (4-tert-Butylcatecholato)zirconocene formed two diastereoisomeric dimers which did not interconvert on the NMR time-scale (DELTA-G double-ended-dagger inter > 90 kJ mol-1) although the intramolecular rearrangement was observed [DELTA-G double ended dagar intra (241 K) = 52 +/- 2 kJ mol-1]. The intermolecular equilibration process probably proceeding via monomeric (catecholato)zirconocene was monitored in the case of the bulky (4-tert-butyl-catecholato)bis(tert-butylcyclopentadienyl)zirconium system by dynamic NMR spectroscopy at high temperature [DELTA-G double ended dagar inter (364 K) = 78 +/- 5 kJ mol-1].

  • Preparation and reaction of metal-ketene complexes of zirconium and titanium

    日期:1982.10
    unsubstituted and alkyl-substituted ketene complexes of titanium and zirconium. Results indicated that the reaction mechanism described in this report can be used to generate a variety of ketene complexes that show a range of reactivities. Their use of models for catalytic intermediates as well as reagents for organometallic and organic synthesis is under further study.

    Reaction of Cp/sub 2/ZrMe/sub 2/ with CpMo(CO)/sub 3/H yields methane and Cp/sub 2/ZrMeMo(CO)/sub 3/Cp (1), which has two terminal carbonyl ligands and a third carbonyl with a low (1545 cm/sup -1/) stretching frequency. Added gaseous CO inserts into the Zr-Me bond in 1 to form the eta/sup 2/-acetyl ligand in 2, Cp/sub 2/Zr(C(O)Me)(OC)Mo(CO)/sub 2/Cp, which is shown by X-ray crystallography to lack
