Project A10 is concerned with the development of new modes of cooperative substrate activation using bifunctional and bimetallic catalysts that comprise imidazolin-2-ylidenaminophosphines (IAPs) as cooperative ligands. IAPs are remarkably strong donor ligands and their electron-releasing character exceeds that of alkylphosphines or N-heterocyclic carbenes. A further characteristic feature is the presence of basic imino-nitrogen atoms attached to the phosphorus atom. Therefore, metal complexes with IAP ligands provide a unique platform for the bifunctional or bimetallic activation of enthalpically strong σ bonds. The potential of IAPs as cooperative ligands in Cu-catalyzed (de)hydrogenation reactions and Ni/Pd-catalyzed cross-coupling reactions will be explored.

项目A10涉及使用包含咪唑啉-2-亚基氨基膦（IAP）作为合作配体的双功能和双功能催化剂的合作底物活化的新模式的开发。IAP是非常强的给体配体，它们的电子释放特性超过了烷基膦或N-杂环卡宾。另一个特征是存在与磷原子相连的碱性亚氨基氮原子。因此，具有IAP配体的金属络合物为双官能或双官能活化化学上强的σ键提供了独特的平台。在铜催化的氢化（脱）反应和镍/钯催化的交叉偶联反应中，IAP作为合作配体的潜力将被探索。
