A low-coordinate iron(ii) complex (Cz(Pz))Fe[N(SiMe)], 1 bearing an NNN-pincer ligand was prepared and fully characterized. Intramolecular C-H activation on the 5-position of a pyrazole at elevated temperatures was observed. Complex 1 was found to be an efficient and chemoselective pre-catalyst for the hydrosilylation of organo carbonyl substrates.
制备并全面表征了一种带有NNN-钳形配体的低配位铁(II)配合物(Cz(Pz))Fe[N(SiMe)],即1。观察到在高温下吡唑5位上的分子内C-H活化。发现配合物1是有机羰基底物硅氢化反应的高效且化学选择性预催化剂。
