摘要：
The insertion of alkenes into an (NHC)copper(1) boryl affords isolable beta-boroalkyl complexes in high yields; competition experiments using substituted styrenes show that electron-donating substituents slow the reaction. Although the insertion products are stable at ambient temperature, a beta-hydride elimination/reinsertion sequence affords a rearranged alpha-boroalkyl complex on heating.
