Disclosed is a process for preparing a cyclopentadienyl group-containing silicon compound or a cyclopentadienyl group-containing germanium compound, comprising reacting (i) a lithium, sodium or potassium salt of a cyclopentadiene derivative with (ii) a silicon halide compound or a germanium halide compound in the presence of a cyanide or a thiocyanate. The cyanide or the thiocyanate is preferably a copper salt. According to the process of the invention, a cyclopentadienyl group-containing silicon compound or a cyclopentadienyl group-containing germanium compound, which is very useful for the preparation of a metallocene complex catalyst component, can be prepared in a high yield for a short period of time.
披露的是一种制备含环戊二烯基团的硅化合物或含环戊二烯基团的锗化合物的过程,包括将(i)环戊二烯衍生物的锂、钠或钾盐与(ii)硅卤化物化合物或锗卤化物化合物在氰化物或硫氰酸盐的存在下反应。氰化物或硫氰酸盐最好是铜盐。根据本发明的过程,可以在短时间内以高产率制备含环戊二烯基团的硅化合物或含环戊二烯基团的锗化合物,这对于制备金属环戊二烯基络合催化剂组分非常有用。
