将烯烃插入到（NHC）铜（1）硼基中以高产率提供可分离的β-硼烷基络合物;使用取代的苯乙烯的竞争实验表明，给电子取代基减缓了反应。虽然插入产物在环境温度下是稳定的，但β-氢化物消除/再插入序列在加热时提供重排的α-硼烷基络合物。
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.
