(NHC)Ni(ii)-catalyzed regioselective hydroalkenylation of norbornene derivatives: fine-tuning of NHC ligands and donor alkenes

Abstract

This study introduced a novel cross-hydroalkenylation approach for addressing a resilient challenge in C5-exo-selective norbornene derivative functionalization. The process, guided by mutual interactions among the NHC–Ni catalyst and the substrate pairs, ensured highly chemo- and regio-selective insertion.
