Iridium complexes have been demonstrated to be highly active catalysts for a wide variety of transformations. Their unique photophysical and photochemical properties render them as one of the most established photocatalysts. Moreover, iridium complexes are widely acknowledged for their efficiency in transfer hydrogenation reactions. However, the development of iridium complexes able to promote both traditional organometallic catalysis and photocatalysis is scarce. Thus, the design of iridium-based catalysts is still an active area of research. In this context, we targeted the synthesis of a family of Ir-Cp* systems to explore their (photo)catalytic applications. Here, we describe the synthesis, structural characterization, and photophysical properties of iridium complexes of formula [IrCp*Cl(N^O)]. These complexes have been applied with a double catalytic function, in transfer hydrogenation for carbonyl reduction and in different photomediated transformations.
铱配合物已被证明是多种转化反应的高效催化剂。它们独特的光物理和光化学性质使其成为最成熟的光催化剂之一。此外,铱配合物在转移氢化反应中的效率也得到了广泛认可。然而,能够同时促进传统有机金属催化和光催化的铱配合物的开发却很少。因此,基于铱的催化剂的设计仍然是一个活跃的研究领域。在此背景下,我们旨在合成一系列Ir-Cp体系,以探索它们的(光)催化应用。在此,我们描述了式[IrCpCl(N^O)]铱配合物的合成、结构表征和光物理性质。这些配合物已被应用于具有双重催化功能的反应中,用于羰基还原的转移氢化反应以及不同的光介导转化反应。
