Аннотация:The reaction of bis[(5a,6,6a,10a,10b-h)-5-phenyl-5,6-dihydroindeno[2,1-b]indol-yl]dimethylsilane dilithium salt with ZrCl4 results in the formation of zirconium ansa-complex
with > 95% rac-selectivity, presumably due to specific crystal structure of the dilithium salt, which was established by X-ray diffraction.
