The discovery of a new reactivity mode for π-arene metal complexes to promote carbon group insertion is reported. The reaction uses ruthenium η⁶-arene complexes supported by a tripodal ligand with enolates derived from α-halo- or α-(tosyloxy)esters to transform π-coordinated arenes to ring-expanded cycloheptatrienes in a single-step dearomatization process.

钌 η6-Arene 配合物的 Arene 环扩展


据报道，发现了一种π-芳烃金属配合物促进碳基团插入的新反应模式。该反应使用钌η⁶-芳烃配合物，由三足配体与源自α-卤代或α-（甲苯磺酰氧基）酯衍生的烯醇化物组成，在一步脱芳烃过程中将π配位的芳烃转化为环膨环庚三烯。
