  Formation of mixed-metal alkoxides mediated by the reactivity of coordinated pinacol

  摘要：

  The addition of pinacol to mixtures of titanium and cerium isopropoxides as well as the use of insoluble titanium and cerium pinacolate synthons was investigated as a route to M-Ce (M=Ti, Nb) species. Pinacol was able to promote the formation of mixed-metal species and the first Ce-Ti and Ce-Nb species namely Ce-2Ti(pin)(2)(OPri)(8) and [M2Ce2(mu(3)-O)(2)(mu,eta(2)pin)(4)(OPri)(6)H-x] [M = Ti, x = 2; M = Nb, x = 0; pin = OCMe2-COMe2] were isolated and characterized by FT-IR and H-1 NMR. The latter were also characterized by X-Ray diffraction. Their structures are based on a rhombus compressed along the M...M direction with 6-coordinated metals. The pinacolate moieties act as bridging-chelating ligands. The metal-oxygen bond lengths vary according to M-O(pin)
