摘要:
A composition is provided comprising a metallocene having the formula of: ##STR1## wherein each Z can be the same or different hydrocarbyl radical selected from the group consisting of cyclopentadienyl, indenyl, tetrahydroindenyl, fluorenyl, and mixtures thereof; each X can be the same or different and is selected from the group consisting of hydrogen, fluorine, chlorine, bromine, iodine, R, OR, NR.sub.2, PR.sub.2, or OQ, or mixtures thereof wherein the R is a C.sub.1 -C.sub.20 hydrocarbyl radical and Q is an inorganic moiety selected from the group consisting of silica, alumina, clay, phosphated alumina, and mixtures thereof; each Y can be the same or different and is an alkyl group, hydrogen, fluorine, chlorine, bromine, iodine, or mixtures thereof; E is selected from C, Sn, Si, Ge, B, Al, N, or P; M is a metal selected from Ti, Zr, Hf, Sc, Y, V, or La; m is a number sufficient to fill out the valences of metal M; and n is 1 or 2. Also provided is a process for preparing the metallocene by contacting a hydrocarbon having an acidic, replaceable hydrogen with an organolithium and an organohalosilane to prepare a ligand which is then contacted with an organo alkali metal compound to form a bridged ligand followed by contacting the bridged ligand with an organolithium and a metal halide. The composition is useful for olefin polymerization, hydrogenation, alkene epoxidation, alkene isomerization, and ketone reduction.
