The introduction of the 2-pyridylsulfenyl directing group to o-carboranes allowed either B(3)-Ir or B(4)-Ir bond formation using a steric effect strategy. Moreover, the reactivity of the B(4)-Rh o-carborane complexes with small molecules was probed by reactions with N-bromosuccinimide, N-iodosuccinimide and O. Rhodium-mediated B(4)-hydroxylation and B(4)-halogenation which are seldom reported have been achieved under practical and mild conditions.
将2-吡啶基亚磺酰基导向基团引入邻碳硼烷，可利用空间效应策略形成B(3)-Ir键或B(4)-Ir键。此外，通过与N-溴代丁二酰亚胺、N-碘代丁二酰亚胺和O的反应，探究了B(4)-Rh邻碳硼烷配合物与小分子的反应活性。在实际且温和的条件下实现了铑介导的B(4)-羟基化和B(4)-卤化反应，这两种反应鲜有报道。
