The Pd-catalyzed reaction between o-iodoallylbenzene and tosylhydrazones gives rise to indene derivatives through a process that involves a carbene migratory insertion followed by an intramolecular carbopalladation, with the formation of two C-C bonds on the same carbon atom. The same strategy has also been applied for the synthesis of 2,3-disubstituted benzofurans and indenones by selecting the appropriate o-substituted iodoarene.
钯催化的邻碘烯丙基苯与甲苯磺酰腙之间的反应通过一个过程生成茚衍生物，该过程涉及卡宾迁移插入，随后是分子内碳钯化，在同一碳原子上形成两个碳-碳键。通过选择合适的邻位取代碘芳烃，同样的策略也已应用于2,3-二取代苯并呋喃和茚酮的合成。
