The manganese hydride dimer, [(BDI)Mn(μ-H)], was found to mediate nitrile dihydroboration, rendering it the first manganese catalyst for this transformation. Stoichiometric experiments revealed that benzonitrile insertion affords [(BDI)Mn(μ-NCHCH)] en route to N,N-diborylamine formation. Density functional theory calculations reveal the precise mechanism and demonstrate that catalysis is promoted by monomeric species.
氢化锰二聚体[(BDI)Mn(μ-H)]被发现可介导腈的二硼氢化反应，使其成为该转化反应的首个锰催化剂。化学计量实验表明，苯甲腈插入反应会生成[(BDI)Mn(μ-NCHCH)]，这是形成N,N-二硼基胺的中间产物。密度泛函理论计算揭示了精确的反应机理，并证明催化作用是由单体物种促进的。
