Abstract
1,2-Bis(cyclooctatetraenyldimethylsilyl)ethane (1) was prepared and co nverted to the corresponding bridged uranocene -bis([8]annulen-yldimet hylsilyl)ethane)uranium(IV) (2). The temperature-dependent NMR spectru m of 2 indicates a flexible molecule that twists between enantiomeric structures with a barrier of about 13 kcal mol-1.
