Sometimes named half-porphyrins, bis-pyrrolic dipyrrin ligands endow their metal complexes with unique properties such as the potential to functionalize the heterocyclic backbone or the meso position and the ability to catalyze interesting chemical transformations. Thus, strategies towards the derivatization of or at the meso group and the use of dipyrrin metal complexes for the formation of a broad range of polypyrrolic derivatives such as 2,2'-bis-dipyrrins, nor-/hetero-corroles and porphynoids have been elaborated. Furthermore, the chelating ability of dipyrrins and the possibility of modifying their steric and electronic characteristics by functionalization can be exploited for the development of numerous complexes featuring appealing properties. Hence, C-H activation/amination, polymerization or oxidation reactions can be catalyzed by dipyrrin metal complexes and classical reagents such as Grignard species, Rh-based or Suzuki-Miyaura catalysts have been revisited by incorporation of dipyrrins in the coordination sphere of the metal cations. This contribution aims to review and illustrate all these aspects, highlighting the potential of these complexes for the design and synthesis of valuable organic compounds and metallo-organic architectures.

基于双吡啶的金属络合物:反应性和催化作用。

双吡咯二吡啶配体有时被称为半卟啉,赋予它们的金属配合物独特的性质,例如使杂环主链或内消旋位官能化的潜力以及催化有趣的化学转化的能力。因此,已经有关于使内消旋基团或在中消旋基团上衍生化的策略,以及使用双吡啶金属配合物形成各种聚吡咯衍生物,例如2,2'-双-二吡咯啉,正-/杂-杂酚和卟啉类的策略。详细说明。此外,可以利用二吡啶酯的螯合能力以及通过功能化修饰其立体和电子特性的可能性来开发许多具有吸引人特性的复合物。因此,CH活化/胺化 可以通过二吡啶金属配合物催化聚合或氧化反应,并且通过在金属阳离子的配位域中引入二吡啶来重新研究经典试剂,例如格氏试剂,Rh基或铃木宫浦催化剂。该贡献旨在审查和说明所有这些方面,强调这些配合物在设计和合成有价值的有机化合物和金属有机结构方面的潜力。
