Abstract
1,2-Bis(cyclooctatetraenyldimethylsilyl)ethane (1) was prepared and converted to the corresponding bridged uranocene ([eta][sup 8]:[eta][sup 8]-1,2-bis([8]annulenyldimethylsilyl)ethane)uranium (IV) (2). The temperature-dependent NMR spectrum of 2 indicates a flexible molecule that twists between enantiomeric structures with a barrier of about 13 kcal mol[sup [minus]1]. 11 refs., 2 figs.
