    摘要： A racemic mixture of a chiral, silicon bridged transition metal metallocene, which is substantially free of meso isomer, is precipitated directly from a reaction mixture as it is formed by reacting an organic solvent solution of an alkali metal salt of a silicon bridged ligand with a transition metal tetrahalide-ether complex.

    摘要： Bridged metallocene compounds are produced by a process of promising commercial utility for plant-sized operations. The overall process involves the direct conversion of benzoindanones to benzoindanols which, without isolation, are converted to benzoindenes. Thereupon the benzoindenes are bridged by deprotonating the benzoindenes with a strong base such as butyllithium and reacting the resultant deprotonated product with a suitable silicon-, germanium- or tin-containing bridging reactant such as dichlorodimethylsilane. The resultant bridged product is deprotonated with a strong base such as butyllithium and reacted with a suitable Group IV, V, or VI metal-containing reactant such as ZrCl.sub.4 to provide a silicon-, germanium- or tin-bridged Group IV, V, or VI metal complex, such as a dihydrocarbylsilyl-bridged zirconocene complex. The initial benzoindenones used in such sequence can be formed readily and in high yield by reaction of a 2-haloacyl halide with naphthalenes unsubstituted in at least the 1- and 2-positions.

    摘要： Bridged metallocene compounds are produced by a process of promising commercial utility for plant-sized operations. One of the key steps of the process involves converting a deprotonated silicon-, germanium- or tin-containing ligand into the metallocene. Preferably, and in accordance with an embodiment of the invention, this is accomplished to great advantage by adding a diamine adduct of a Group IV, V, or VI metal tetrahalide to a solution or slurry formed from a deprotonated silicon-, germanium- or tin-containing ligand and an organic liquid medium so as to form a metallocene. The overall process of the invention involves the direct conversion of benzoindanones to benzoindanols which, without isolation, are converted to benzoindenes. Thereupon the benzoindenes are bridged by deprotonating the benzoindenes with a strong base such as butyllithium and reacting the resultant deprotonated product with a suitable silicon-, germanium- or tin-containing bridging reactant such as dichlorodimethylsilane. The resultant bridged product is deprotonated with a strong base such as butyllithium and reacted with a suitable Group IV, V, or VI metal-containing reactant such as ZrCl.sub.4 to provide a silicon-, germanium- or tin-bridged Group IV, V, or VI metal complex, such as a dihydrocarbylsilyl-bridged zirconocene complex.
