In the examples which illustrate the practice of the invention the analytical techniques described below were employed for the analysis of the resulting polyolefin products. Molecular weight determinations for polyolefin products were made by Gel Permeation Chromatography (GPC) according to the following technique. Molecular weights and molecular weight distributions were measured using a Waters 150 gel permeation chromatograph equipped with a differential refractive index (DRI) detector and a Chromatix KMX-6 on-line light scattering photometer. The system was used at 135� C. with 1,2,4-trichlorobenzene as the mobile phase. Shodex (Showa Denko America, Inc.) polystyrene gel columns 802, 803, 804 and B05 were used. This technique is discussed in "Liquid Chromatography of Polymers and Related Materials III", J. Cazes editor, Marcel Dekker, 1981, p. 207 which is incorporated herein by reference. No corrections for column spreading were employed; however, data on generally accepted standards, e.g. National Bureau of Standards Polyethylene 14B4 and anionically produced hydrogenated polyisoprenes (an alternating ethylene-propylene copolymer) demonstrated that such corrections on Mw/Mn (=MWD) were less than 0.05 units. Mw/Mn was calculated from elution times. The numerical analyses were performed using the commercially available Beckman/CIS customized LALLS software in conjunction with the standard Gel Permeation package, run on a HP 1000 computer.
Compound A: Part 1. Me4 HC5 Li (10.0 g, 0.078 mol) was slowly added to a Me2 SiCl2 (11.5 ml, 0.095 mol, in 225 ml of tetrahydrofuran (thf) solution). The solution was stirred for 1 hour to assure complete reaction. The thf solvent was then removed via a vacuum to a cold trap held at -196� C. Pentane was added to precipitate out the LiCl. The mixture was filtered through Celite. The solvent was removed from the filtrate. Me4 HC5 SiMe2 Cl (15.34 g, 0.071 mol) was recovered as a pale yellow liquid.
Part 2. Me4 HC5 SiMe2 Cl (10.0 g, 0.047 mol) was slowly added to a suspension of LiHN-t-Bu (3.68 g, 0.047 mol, ˜100 ml thf). The mixture was stirred overnight.

The ether was removed via a vacuum to a cold trap held at -196� C. Pentane was added to precipitate out the LiCl. The mixture was filtered through Celite twice. The pentane was significantly reduced in volume and the pale yellow solid was filtered off and washed with solvent. Me2 Si(Me4 C5)(N-t-Bu)ZrCl2 (1.07 g, 0.0026 mole) was recovered. Additional Me2 Si(Me4 C5)(N-t-Bu)ZrCl2 was recovered from the filtrate by repeating the recrystallization procedure. Total yield, 1.94 g, 0.0047 mol).
Compound C: Part 1. Me2 SiCl2 (7.5 ml, 0.062 mol) was diluted with ˜30 ml thf.

Part 4. Li2 [Me2 Si(Me3 SiC5 H3)(N-t-Bu)].3/4Et2 O (1.44 g, 0.0043 mol) was suspended in ˜50 ml of ether. ZrCl4 (1.0 g, 0.0043 mol) was slowly added and the reaction was allowed to stir for a few hours. The solvent was removed via vacuum and pentane was added to precipitate the LiCl. The mixture was filtered through Celite, and the filtrate was reduced in volume. The flask was placed in the freezer (-40� C.) to maximize precipitation of the product. The solid was filtered off giving 0.273 g of an off white solid. The filtrate was again reduced in volume, the precipitate filtered off to give an additional 0.345 g for a total of 0.62 g of the compound with empirical formula Me2 Si(Me3 SiC5 H3)(N-t-Bu)ZrCl2. The x-ray crystal structure of this product reveals that the compound is dimeric in nature.
