With this project, substantial deficits in two areas of oxidation = deelectronation chemistry shall be advanced. The developed methods – Innocent and Ligand-forming Oxidant Salts – shall provide straight-forward access to stable weakly coordinating anion salts of the hitherto underdeveloped area of metal-arene-complex cations [Mx(arene)y]n+ with M being from Group 2 as well as Groups 3 to 5. We expect that the target metal cations retain a substantial amount of Lewis acidity / electrophilicity in this non-conventional coordination environment. Thus, the metal-arene-complexes will be used for orienting applications, i.e. either for selected substitution reactions with non-conventional ligands or olefin/epoxide polymerization e.g. with ansa-arene ligands.

有了这个项目，氧化=去电子化学的两个领域的重大缺陷将被推进。开发的方法-无辜和配体形成氧化剂盐-将提供直接获得金属-芳烃络合物阳离子[Mx（芳烃）y]n+的迄今未开发区域的稳定弱配位阴离子盐，其中M来自第2族以及第3至5族。我们预期目标金属阳离子在这种非常规配位环境中保持大量的刘易斯酸性/亲电性。因此，金属-芳烃络合物将用于定向应用，即用于与非常规配体的选择的取代反应或烯烃/环氧化物聚合，例如与柄型芳烃配体的聚合。
