Title: Tripodal cyclopentadiene derivatives and their use

Abstract: Novel tripodal cyclopentadiene derivatives have the formula (I) ##STR1## where E are identical or different and are --N(R)(R), --P(R)(R), --As(R)(R), --Sb(R)(R), --OR, --SR, --SeR, --TeR, where R are identical or different and are each hydrogen, a C.sub.1 -C.sub.20 -carboorganic radical or a C.sub.1 -C.sub.30 -organosilicon radical, or E is a leaving group X and R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6 are identical or different and are each hydrogen, a C.sub.1 -C.sub.20 -carboorganic radical or a C.sub.1 -C.sub.30 -organosilicon radical, Z is a cyclopentadienyl radical or a substituted cyclopentadienyl structural unit and T is hydrogen, a C.sub.1 -C.sub.20 -carboorganic radical or a C.sub.1 -C.sub.30 -organosilicon radical or a group E--Y--, where E is --N(R)(R), --P(R)(R), --As(R)(R), --Sb(R)(R), --OR, --SR, --SeR, --TeR or a leaving group X, where R are identical or different and are each hydrogen, a C.sub.1 -C.sub.20 -carboorganic radical or a C.sub.1 -C.sub.30 - organosilicon radical and Y is a C.sub.1 -C.sub.20 -organic group which connects E to C.sup.1.
