Zirconocene Functional Group Chemistry: Photochemical [4+4] Cycloaddition of Isoprenyl Sidechains to the Bent Metallocene Framework

Autor: Ingo Greger, Gerhard Erker, Gerald Kehr

Publikováno v: European Journal of Inorganic Chemistry. 2010:4711-4715

The 4-isoprenyl- and 1-isoprenylcyclopentadienides 6a and 6b were prepared by means of a fulvene route involving a subsequent deprotonation reaction using potassium hexamethyldisilylamide. Transmetallation to zirconium or hafnium gave the respective

Dynamic Topochemical Reaction Control−A Principle and Its Application in ansa-Metallocene Synthesis

Autor: Gerhard Erker, Ingo Greger, Gerald Kehr, Roland Fröhlich

Publikováno v: Organometallics. 29:3210-3221

The Cp-alkenyl and Cp-dienyl ligand systems 5 and 8 were prepared by fulvene routes. Subsequent transmetalation gave the respective (Cp-propenyl)2-, (Cp-butenyl)2-, (Cp-pentadienyl)2-, and (Cp-hexadienyl)2ZrCl2 and -HfCl2 complexes 6, 9, and 10. In t

Functional Group Chemistry at the Group 4 Bent Metallocene Framework: [2+2] Cycloaddition of the Parent Bis(vinyl-Cp/vinyl-Ind)ZrCl2 Systems

Autor: Gerald Kehr, Ingo Greger, Gerhard Erker, Roland Fröhlich

Publikováno v: Organometallics. 29:860-866

Bis(vinyl-Cp)zirconium dichloride (6) undergoes a clean intramolecular photochemically induced [2+2] cycloaddition reaction to yield the cyclobutylene-bridged ansa-zirconocene isomer (7) when irrad...
