Abstract
We report a unique class of dinitrogen complexes of iron featuring sulfur donors in the ancillary ligand. The ligands utilized are related to the recently studied tris(phosphino)silyl ligands (2-R(2)PC(6)H(4))(3)Si (R = Ph, iPr) but have one or two phosphine arms replaced with thioether donors. Depending on the number of phosphine arms replaced, both mononuclear and dinuclear iron complexes with dinitrogen are accessible. These complexes contribute to a desirable class of model complexes that possess both dinitrogen and sulfur ligands in the immediate iron coordination sphere.
摘要
我们报告了一类独特的含硫配体的铁系二氮配合物。所使用的配体与最近研究的三（膦基）硅基配体（2-R（2）PC（6）H（4））（3）Si（R = Ph，iPr）有关，但有一个或两个膦基臂被硫醚供体取代。根据取代膦基臂的数量，单核和双核铁配合物都可以得到二氮。这些配合物构成了一类理想的模型配合物，它们在铁的配位球中同时含有二氮和硫配体。
