Dimethylzirconocene and dihydridozirconocene both catalyze the dehydrogenative coupling of primary and secondary organosilanes. Primary silanes give linear polysilanes and secondary silanes give tetraorganodisilanes. The reaction of dimethylzirconocene with a small excess of phenylsilane gives the unusual unsymmetrically substituted zirconocenesilylhydride dimer: Cp2Zr(SiMePhH)(μ-H)2(PhH2Si)ZrCp2. The structure of this product is deduced from a combination of nmr and crystallographic results. Although the nmr data suggest that dihydridozirconocene reacts with phenylsilane to give the corresponding symmetrical dimer (Me replaced by H) in solution, attempts to isolate this compound have not been successful.

Ultrastructural Findings

Characterization of Borrelia burgdorferi strains by means of negative staining EM has become an integral part of many studies related to the biology of the Lyme disease organism. However, relying solely upon negative staining to compare new isolates with prototype B31 or other borreliae is often unsatisfactory. To obtain more satisfactory results, we have relied upon a correlative approach encompassing a variety EM techniques, i.e., scanning for topographical features and cryotomy, negative staining and thin sectioning to provide a more complete structural characterization of B. burgdorferi.For characterization, isolates of B. burgdorferi were cultured in BSK II media from which they were removed by low speed centrifugation. The sedimented borrelia were carefully resuspended in stabilizing buffer so as to preserve their features for scanning and negative staining. Alternatively, others were prepared for conventional thin sectioning and for cryotomy using modified procedures. For thin sectioning, the fixative described by Ito, et al.
