Trapping of AlMe3 with the Oxygen Atom of the Zr3(μ3-O) Unit
摘要:
We report for the first time the direct complexation of AlMe3 by a Zr-3(mu(3)-O) core. The precursor [Zr-4(mu(4)-O)(mu-OMe)(6)Cl-8(thf)(4)] (1) was obtained in the direct reaction of ZrCl4 with methanol. When 1 was allowed to react with AlMe3, [Zr3Al(mu(4)-O)(mu-OMe)(6)Cl-6(Me)(thf)(3)] (2) was isolated. An analogous trend was observed in the compound [Zr4Al2(mu(4)-O)(2)(OEt)(12)Cl-6] (3), which was obtained in the direct reaction of ZrCl4 with Zr(OEt)(4) and Al in thf/EtOH.
