在过去的十年中，金属块催化经历了从一个深奥的好奇心到一个成熟和巩固的可持续合成领域的转变。稀土金属如Ca、Mg和Al在硅氢化、氢胺化或烯烃聚合等关键催化过程中表现出令人大开眼界的催化性能。在这些研究的同时，s-block混合金属试剂也引起了科学家们的广泛兴趣。这些双金属试剂影响许多基础有机转化，通常比传统的单金属试剂提供增强的反应性和更好的化学和区域选择性。尽管迄今为止在合成方面取得了重大进展，但大多数努力主要集中在化学计量转换上。结合这两个令人兴奋的研究领域，本文概述了s/p-block协同催化这一新兴概念。展示了世界各地几个研究小组最近的贡献，讨论了这些系统在催化转化中未开发的潜力，特别强调了协同效应如何运作以及每种金属在这些转化中发挥的特殊作用。促进对s-嵌段协同催化基本规则的理解，这些双金属系统在催化转化的关键选择中的应用，包括氢胺化、环化、硼氢化到C-C键形成过程，以及它们在重要聚合反应中的应用。本展望将主要基团杂双金属试剂的协同效应输出到催化体系，展示了它们在加氢、环化、C-C键形成和聚合过程中的应用的关键进展。
Over the past decade s-block metal catalysis has undergone a transformation from being an esoteric curiosity to a well-established and consolidated field towards sustainable synthesis. Earth-abundant metals such as Ca, Mg, and Al have shown eye-opening catalytic performances in key catalytic processes such as hydrosilylation, hydroamination or alkene polymerization. In parallel to these studies, s-block mixed-metal reagents have also been attracting widespread interest from scientists. These bimetallic reagents effect many cornerstone organic transformations, often providing enhanced reactivities and better chemo- and regioselectivities than conventional monometallic reagents. Despite a significant number of synthetic advances to date, most efforts have focused primarily on stoichiometric transformations. Merging these two exciting areas of research, this Perspective Article provides an overview on the emerging concept of s/p-block cooperative catalysis. Showcasing recent contributions from several research groups across the world, the untapped potential that these systems can offer in catalytic transformations is discussed with special emphasis placed on how synergistic effects can operate and the special roles played by each metal in these transformations. Advancing the understanding of the ground rules of s-block cooperative catalysis, the application of these bimetalic systems in a critical selection of catalytic transformations encompassing hydroamination, cyclisation, hydroboration to C–C bond forming processes are presented as well as their uses in important polymerization reactions. Exporting cooperative effects in main group heterobimetallic reagents to catalytic regimes, this Perspective showcases key advances in their applications for hydroelementation, cyclisation, C–C bond formation and polymerization processes.
