Reactions of Zirconacyclopentadienes with Nitrosobenzene. Characterization of Zirconacycle Intermediates and Formation of <i>N</i>-Phenylpyrroles

Nitrosobenzene inserts into the Zr−C bond of zirconacyclopentadienes to give seven-membered zirconacyclic rings. The resulting insertion products are readily converted to <i>N</i>-phenylpyrroles and (in one case) a 3,3-spiroindole derivative.
