Beiträge zur Chemie der Alkylverbindungen von Übergangsmetallen. XLII. Untersuchungen über Norbornylverbindungen des Titans,Zirconiums und Hafniums

Contributions to the Chemistry of Transition Metal Alkyl Compounds. XLII. Investigations on Norbornyl Compounds of Titanium, Zirconium, and Hafnium It is reported about ¹³C-NMR, IR, and mass spectroscopic measurements of (1-Nor)₄M derivatives of Ti, Zr, and Hf and unsuccessful efforts for synthesis of 1-norbornyl titanium halides Furthermore, (2-Nor)₄Ti and (2-Nor)₄Zr were synthesized. These compounds are remarkably less stable than the corresponding 1-norbornyl derivatives and appear to be exo/endo isomer mixtures. At thermolyses of (2-Nor)₄Ti stable (2-Nor)₂Ti is formed. The stability of (7-Nor)₄Ti is comparable with that of (2-Nor)₄Ti.
