We have investigated the capacity of a range of structurally-diverse, photoactive rhenium(i) tricarbonyl complexes featuring either tetrazolato or N-heterocyclic carbene (NHC) ligands to facilitate fundamental classes of visible-light-mediated photoredox-catalysed reactions. In this study, we demonstrate that these systems mediate representative atom-transfer radical addition, hydrodehalogenation, and α-amino C-H functionalisation reactions. These rhenium(i) complexes provide greater or at least comparable reactivity to the prototypical photoredox catalyst [Ru(bpy)] in many cases.
我们研究了一系列结构多样、具有四唑或N-杂环卡宾（NHC）配体的光活性铼（I）三羰基配合物促进可见光介导的光氧化还原催化反应基本类型的能力。在本研究中，我们证明这些体系介导了代表性的原子转移自由基加成、加氢脱卤和α-氨基C-H官能化反应。在许多情况下，这些铼（I）配合物比典型的光氧化还原催化剂[Ru（bpy）]具有更高或至少相当的反应活性。
