本文首次报道用两相法(C~6H~6/H~2O)合成二茂锆二芳氧基配合物,并与绝对无水条件下的合成结果进行了比较,共合成了五个新的配合物, 同时对二氧二茂锆的环戊二烯基钠合成法加以改进,使产率由66%提高到81%.

The CpNa(CP = cyclopentadienyl) synthetic method of Cp2ZrCl2 was improved and the yield was raised from 66 to 81%. A simple interfacial synthetic method of biscyclopentadienylzirconium diaromatoxide compounds was reported and the anhydrous synthesis of these compounds was also carried out. Several new compounds, Cp2Zr(OAr)2 (Ar = 4-PhCH2C6H4, 3,4-MeClC6H3, 3-O2NC6H4, 4-O2NC6H4, 3-H2NC6H4), were synthesized and characterized with IR, 1H NMR and elemental anal.
