The use of metallodendrimers in various applications such as catalysis and biology has highlighted the potential for the development of polynuclear metal-based complexes. This review provides a more focused overview of the developments in the application of metallodendrimers as catalysts for the hydroformylation reactions involving olefins. Specific attention is drawn to the influence of these dendritic scaffolds on the activity as well as the chemo- and regioselectivity afforded by the catalyst itself. We furthermore emphasize the recyclability of the rhodium-bearing metallodendrimers via heterogenization of homogeneous catalysts. Recyclable and reusable catalyst precursors are attractive in championing the sustainable use of mineral resources, especially where rare, expensive, and fast-depleting metals such as rhodium are of prime importance.

金属树枝状聚合物在催化和生物学等各种应用中的使用凸显了多核金属基配合物的开发潜力。这篇综述更集中地概述了金属树枝状大分子作为涉及烯烃的加氢甲酰化反应的催化剂的应用进展。特别注意这些树枝状支架对催化剂本身提供的活性以及化学和区域选择性的影响。我们还通过均相催化剂的异质化进一步强调了含铑金属树枝状聚合物的可回收性。可回收和可重复使用的催化剂前体在支持矿物资源的可持续利用方面具有吸引力，特别是在铑等稀有、昂贵和快速消耗的金属至关重要的情况下。
