[2+2+2]环加成反应是一个令人着迷的过程,它由三个不饱和度组装成六元环,具有完全的原子经济性。在可用于催化该反应的多种过渡金属中,铑具有许多优点。这些包括高活性和多功能性,但尤其是通过修饰金属周围的配体来轻松调节反应性和选择性的能力。在这篇个人文章中,我们总结了我们在开发高效且可持续的[2+2+2]环加成反应以制备感兴趣的产物、开发催化剂可以回收和再利用的条件以及了解控制过程选择性的机制细节方面所做的努力。
[2+2+2] Cycloaddition reaction is a captivating process that assembles six-membered rings from three unsaturations with complete atom economy. Of the multiple transition metals that can be used to catalyze this reaction, rhodium offers many advantages. These include high activity and versatility, but especially the ability to easily tune the reactivity and selectivity by the modification of the ligands around the metal. In this personal account, we summarize our endeavours in the development of efficient and sustainable [2+2+2] cycloaddition reactions to prepare products of interest, develop conditions in which the catalyst can be recovered and reused, and understand the mechanistic details that govern the selectivity of the processes.
