The two electron reduction of iron complexes [(PP)Fe(Cl)] (R = Ph or tBu) 2a-b afforded complexes [(PP)Fe(N)] 4a-b. Protonation of 4a at the metal center and subsequent reduction to Fe(i)-H species lead to complex [(PP)Fe(N)(H)] 6avia a spontaneous disproportionation reaction. Complex 4a behaves as one of the most efficient monometallic Fe-catalysts reported to date for N-to-N(SiMe) functionalization under atmospheric pressure.
[(PP)Fe(Cl)] (R = Ph 或 tBu) 2a-b 的二电子还原得到配合物 [(PP)Fe(N)] 4a-b。4a 在金属中心质子化并随后还原为 Fe(i)-H 物种，导致配合物 [(PP)Fe(N)(H)] 6a 通过自发歧化反应生成。在大气压下，配合物 4a 是迄今为止报道的用于 N 到 N(SiMe) 官能化的最有效的单金属 Fe 催化剂之一。
