资源简介：
A series of triiron
complexes supported by a tris(β-diketiminate)cyclophane
(L3–) catalyze the reduction of dinitrogen
to tris(trimethylsilyl)amine using KC8 and Me3SiCl. Employing Fe3Br3L affords
83 ± 7 equiv of NH4+/complex after protonolysis,
which is a 50% yield, based on reducing equivalents. The series of
triiron compounds tested evidence the subtle effects of ancillary
donors, including halides, hydrides, sulfides, and carbonyl ligands,
and metal oxidation state on N(SiMe3)3 yield,
and highlight Fe3(μ3-N)L as
a common species in product mixtures. These results suggest that ancillary
ligands can be abstracted with Lewis acids under reducing conditions.
