摘　　要：由于锆类有机金属化合物在催化等方面的应用价值,陈寿山等合成了一系列四环戊二烯基二芳氧基-μ-氧合二锆衍生物。Tetrakis (cyclopentadienyl) di(aryloxy) - μ-oxodizirconiums have been separated using sjlica gel as stationary phase and petroleum ether-acetone (15:1,10:1,7:l)or cyclohexane-dichloroethane (25:1) as developer for thin-layer chroma-tography, and petroleum ether-acetone(3:1) or petroleum ether-tetrahydrofuran (25:1) as mobile phase for high performance liquid chromatography. The following rules for different substitutions have been obtained:1. Rf(p-Cl)<Rf(m-Cl).tR(p-Cl)>tR(m-Cl)2. Rf(o-CH3)>Rf(m-CH3)≈Rf(p-CH3) tR(o-CHs)<tR(m-CH3)≈tR(p-CH3).3. Rf(alkyl substituted)>Rf(nonsubstituted)> Rf(halogen substituted)tR(halogen substituted)>tR(nonsubsti-tuted)>tR(alkyl substituted).
