新型茂金属齐格勒催化剂是通过用甲基铝氧烷活化刚性柄型茂金属 2 生成的。配合物 2 是通过应用配合物 1 的酸催化曼尼希反应（一种来自有机合成库的经典反应）形成的，该反应可以通过富烯途径轻松获得。
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.
