chiral and achiral NCN pincer Fe complexes containing bis(oxazolinyl)phenyl (abbreviated as phebox) ligands with SnMe3, SiMe3, Me, and Ph ligands were investigated. Irradiation of (phebox)SnMe3 (2) with 1 equiv of Fe(CO)5 led to oxidative addition to give NCN pincer stannyl complex (phebox)Fe(CO)2(SnMe3) (3). Similarly, oxidative addition of (phebox)SiMe3 (4) with Fe(CO)5 resulted in the formation of
研究了含有双(恶唑啉基)苯基(缩写为phebox)配体与SnMe 3,SiMe 3,Me和Ph配体的手性和非手性NCN钳制Fe络合物的制备和反应性。用1当量的Fe(CO)5辐照(phebox)SnMe 3(2)导致氧化加成,得到NCN夹钳式苯乙烯基配合物(phebox)Fe(CO)2(SnMe 3)(3)。类似地,将(phebox)SiMe 3(4)与Fe(CO)5氧化添加导致形成甲硅烷基络合物(phebox)Fe(CO)2 SiMe 3(5)。Me和Ph配合物(phebox)Fe(CO)2 R(7,R = Me; 8,R = Ph)通过溴化配合物(phebox)Fe(CO)2 Br(1)与ZnMe 2和分别为ZnPh 2。这些phebox Fe络合物可作为酮的氢化硅烷化和N-甲基吲哚的CH甲硅烷基化的催化剂。
