为了利用铁的络合物作为催化剂，设计良好的配体的应用是控制铁中心的反应活性的关键。最近，本课题组成功地合成了含吡咯烷基PNP钳形配体的铁络合物，并将其应用于温和的反应条件下将氮气催化转化为氨。作为一项广泛的研究，我们报道了铁催化的炔烃与频碳硼烷的氢硼化反应，其中选择性地获得了相应的E-异构体。
To utilize iron complexes as catalysts, the application of a well-designed ligand is critical to control the reactivity of the iron center. Recently, our group has succeeded in the synthesis of iron complexes bearing a pyrrolide-based PNP pincer ligand and their application to the catalytic transformation of dinitrogen into ammonia under mild reaction conditions. As an extensive study, we report the iron-catalyzed hydroboration of alkynes with pinacolborane, where the corresponding E-isomers are obtained selectively.
