A pincer-type Ru(II)-NNP complex bearing a pyrazolyl-(NH-PtBu₂)-pyridine ligand was synthesized and structurally characterized by NMR, IR, elemental analysis, and X-ray single-crystal crystallographic determinations, which efficiently catalyzed the synthesis of multisubstituted pyrroles and pyridines by means of the reactions of secondary alcohols and β- or γ-amino alcohols through deoxygenation and selective C–N and C–C bond formation. The coupling reactions took place with 0.3 mol % catalyst loading and tolerated diverse functional groups. The present work provides an alternative method to construct highly active transition-metal complex catalysts from readily available ligands.

通用的Ru（II）-NNP复合催化剂，用于合成多取代的吡咯和吡啶

合成了带有吡唑基-（NH-P t Bu ₂）-吡啶配体的钳型Ru（II）-NNP络合物，并通过NMR，IR，元素分析和X射线单晶晶体学测定对其结构进行了表征，通过仲醇与β-或γ-氨基醇的脱氧反应以及选择性C–N和C–C键的形成，有效地催化了多取代吡咯和吡啶的合成。偶联反应以0.3mol％的催化剂负载量和容许的各种官能团进行。本工作提供了一种从容易获得的配体中构建高活性过渡金属配合物催化剂的替代方法。
