  A novel process of preparing tridentate ligands containing one or more of a diarylphosphine and/or dialkylphosphine electron donating groups are disclosed. Use of this process for preparing a combinatorial library of such tridentate ligands and of organometallic complexes containing same is also disclosed. Further disclosed are novel diarylphosphine-containing and dialkylphosphine-containing compounds that can serve as tridentate ligands (e.g., pincer ligands), combinatorial libraries of such tridentate ligands, organometallic complexes containing these ligands (e.g., pincer complexes), and combinatorial libraries of such complexes. Methods utilizing these libraries for screening for candidate organometallic catalysts are also disclosed. Novel precursor molecules useful for preparing the tridentate ligands and processes of preparing same are also disclosed.

• Versatile, Selective, and Switchable Coordination Modes of Pincer Click Ligands

  Ligands possessing multiple complexation modes are an interesting class of compounds. Here we report that our recently established pincer click ligands (PCLs), prepared by copper-catalyzed cycloaddition of azides to alkynes, exhibit unique versatility in coordination ability. Nitrogens of the triazole-based backbone can actively participate in metal ligation rather than being a spectator backbone.

  具有多种络合模式的配体是一类有趣的化合物。在这里我们报告说，我们最近建立的通过铜催化的叠氮化物与炔烃的环加成反应制备的钳型单击配体（PCL）在配位能力方面表现出独特的多功能性。基于三唑的骨架的氮可以积极地参与金属连接，而不是成为观众的骨架。在反应条件的选择下，这些配体在与金属前体反应时可以选择性地获得双齿或三齿配位。制备了具有不同配位模式的钯和铂配合物，并对其进行了全面表征，包括X射线分析。此外，证明了动力学上优选的二齿络合物向热力学控制的三齿物种的“翻转转换”。
