Consider the preparation of the N-G-N linked complex 6, below. An indenoindole compound is first prepared by reacting 6-methyl-1-indanone and p-tolylhydrazine. Deprotonation of the indenoindole at nitrogen, followed by reaction with 0.5 eq. of dichlorodimethylsilane gives a bis(indeno[1,2-b]indolyl)dimethylsilane (5). This neutral compound is doubly deprotonated and then reacted with 2 eq. of cyclopentadienyl-zirconium trichloride to give the desired bimetallic complex, 6. A similar approach is used to generate phenylboranyl complex 8.
