The focus of this project is on the understanding and further development of the activation of dioxygen in molecular metal siloxide systems. The aim is to investigate how the activation can be influenced and how subsequent steps proceed, respectively, to arrive at functional systems employable for the oxyfunctionalization of hydrocarbons. Hence, the project is not concerned primarily with finding catalysts that show high TOFs and TONs but rather with fundamental, stoichiometric investigations for the directed construction of novel homo- and heterobimetallic superoxido, peroxide and oxido metal moieties as well as with the discovery of new elemental steps. Of course such insights in the medium term form the basis for the development of catalytic/applicable systems, and whenever this is obvious research in this direction will be carried out.

该项目的重点是理解和进一步发展分子金属硅氧化物体系中的分子氧活化。我们的目的是调查如何激活可以受到影响，以及如何进行后续步骤，分别到达可用于烃的氧官能化的功能系统。因此，该项目主要不关注寻找显示高TOF和TON的催化剂，而是关注用于定向构建新型均相和杂相超氧化物、过氧化物和氧化物金属部分的基本化学计量研究，以及发现新的元素步骤。当然，这种中期见解构成了催化/适用系统开发的基础，只要这一点很明显，就会在这一方向进行研究。
