The formation of new homogeneous catalysts for 1-alkene polymerization and for alkene copolymerizations, especially with polar or functionalized co-monomers, requires the development of novel ligand frameworks and the use of specially suited activator components. In this project we want to develop synthetic routes to [3]ferrocenophane and C3-ansa-group 4 metallocene ligand systems bearing pairs of suitable donor substituents for their use as rigid chelate ligands. In this way, novel late transition metal catalysts (Ni, Pd) for 1-alkene/CO copolymerization will be formed, as well as early/late heterobimetallic catalysts, where intramolecular chain transfer is hoped to influence the copolymerization processes to be carried out at these systems after suitable activation. Both synthetic series will rely on a novel Mannich-type carbon-carbon coupling reaction that can be carried out in the ligand sphere of even very sensitive organometallic systems. A variant of this reaction type will be used to prepare a novel type of "constrained geometry" catalysts, that is expected to be of especial interest in olefin copolymerization catalysis.

用于1-烯烃聚合和烯烃共聚（特别是与极性或官能化共聚单体）的新的均相催化剂的形成需要开发新的配体框架和使用特别适合的活化剂组分。在这个项目中，我们希望开发合成路线，[3]二茂铁和C3-柄型-第4族金属茂配体系统轴承对合适的供体取代基，用于其作为刚性螯合配体的使用。通过这种方式，将形成用于1-烯烃/CO共聚的新型后过渡金属催化剂（Ni、Pd），以及早期/晚期杂双金属催化剂，其中分子内链转移希望影响在这些体系中进行的共聚过程适当的活化后。这两个合成系列将依赖于一种新的曼尼希型碳-碳偶联反应，该反应可以在甚至非常敏感的有机金属体系的配体球中进行。这种反应类型的变体将用于制备新型的“受限几何”催化剂，预期其在烯烃共聚催化中特别有意义。
