摘要:
A simple new route to access heterometallic alkoxo precursors for a wide range of materials is repoiled. This unique synthetic method comprises elimination of the cyclopentadienyl ring from CP2MCl2 (M = Ti, Zr) as CpH in the presence of M'(OR)(2) (M' = Ca, Mn; OR = OCH2CH2OCH3 or OEt) in an alcohol as a source of protons. In one-pot reactions, we have prepared four different compounds with Ti2Ca4(mu(6)-O), CP2Zr2Ca4(mu(4)-Cl), ZrjoMn(10)(mu(3)-O)(14), and CP3Ti2(mu-OEt)(2) motifs. The compounds were characterized by single-crystal X-ray structural analysis and NMR spectroscopy.
