  Reaction of (C₅Me₅)₂Yb(ER)(NH₃) with Me₃Al. Formation of (C₅Me₅)₂Yb(AlMe₄) and [(C₅Me₅)₂Yb(ER)(AlMe₃)₂]₂

  摘要：

  Addition of 3 molar equiv of AlMe3 to (Me5C5)(2)Yb(ER)(NH3) gives two types of products depending on the identity of the ER group. When ER is OSiMe3 or TePh, the isolated metallocene is [(Me5C5)(2)Yb(Me4Al)](2), which exists as an equilibrium between monomeric and dimeric forms in toluene solution. When ER is OCMe3, SPh, S-p-tolyl, or SePh, the isolated metallocenes have the stoichiometry (Me5C5)(2)Yb(ER)(Me3Al)(2). The H-1 NMR spectra of these molecules show that several species are present in solution. The crystal structure of the S-p-tolyl derivative shows that two (Me5C5)(2)Yb fragments are bridged by two Me3Al(S-p-tolyl)AlMe3 units by way of nearly linear Yb...H3C-Al bonds.

  monomeric complex tBuAl[OC(C6H5)2C(C6H5)2O](C4H8O) (3). Reactions of Me3Ga and Me3In with benzopinacol yielded trinuclear complexes Me5M3[OC(C6H5)2C(C6H5)2O]2 (4 (M = Ga), 5 (M = In)), isostructural to compound 1. In the presence of water and alcohols, compounds 4 and 5 underwent a decomposition reaction to benzopinacol and a mixture of metalloxanes and alkoxides.
