N-Heterocyclic Carbene Dichotomy in Pd-Catalyzed Acylation of Aryl Chlorides via C–H Bond Functionalization
摘要:
The first Pd-catalyzed intramolecular acylation of aryl chlorides via C-H bond functionalization is presented. The method allows for the synthesis of a variety of elusive benzocyclobutenones with a wide range of functional groups and substitution patterns. We demonstrate that a change in the ligand backbone dictates the selectivity pattern.

Phthalides 1a-f were treated with prop-2-ynylmagnesium bromide followed by treatment with 20% HCl in one pot to give the corresponding seven-membered cyclic ethers, benzoxepins 4a-f.
