Abstract
New metallocene Ziegler catalysts are generated by activation of the rigid ansa-metallocenes 2 with methylalumoxane. Complexes 2 are formed by application of an acid-catalyzed Mannich reaction—a classical reaction from the synthetic organic repertoire—of complexes 1, which are readily available by means of a fulvene route.
