In this tutorial, we describe the applications of well-defined heterobimetallic complexes in coordination insertion polymerization catalysis. The presence of two different metals in a single catalyst platform imparts reactivity patterns that are distinct from those of their homobimetallic and monometallic counterparts. We will demonstrate that heterobimetallic complexes are a versatile and unique class of catalysts by providing representative examples from recent studies of carbon dioxide/epoxide, lactone, lactide, and olefin polymerization. We will focus on the various strategies employed to synthesize mixed metal species, methods to characterize their structures, and the mechanistic roles of the metal ions during polymerization.

在本教程中，我们描述了定义明确的异双金属配合物在配位插入聚合催化中的应用。单一催化剂平台中两种不同金属的存在赋予了不同于其同双金属和单金属对应物的反应性模式。通过提供二氧化碳/环氧化物，内酯，丙交酯和烯烃聚合的最新研究的代表性实例，我们将证明杂双金属配合物是一种多用途且独特的催化剂。我们将重点介绍用于合成混合金属物种的各种策略，表征其结构的方法以及聚合过程中金属离子的机械作用。
