3SiC2SiMe3) (L = pyridine, 3; L = (S)-(−)-nicotine, 4). In the reaction of 2 with acetone the insertion product rac-(EBTHI)(ZrOCMe2C(SiMe3)C(SiMe3), 5, was formed. Complex 2 reacted with 2 equiv of PhNCHPh with substitution of the alkyne to form rac-(EBTHI)ZrNPhCHPhCHPhNPh, 6. Compounds 2 and 6 were characterized by an X-ray structure analysis.
