We recently reported a reaction sequence that activates C–H bonds in simple arenes as well the N–N triple bond N2, delivering aryl group to N2 form new N–C (Nature 2020, 584, 221). This enables transformation of abundant feedstocks (arenes and N2) into N-containing organic compounds. The key forming step occurs upon partial silylation N2. However, pathway through which reduction, silylation, migration occurred was unknown. Here, we describe synthetic, structural, magnetic, spectroscopic,...
High-valent iron alkyl complexes are rare, as they prone to Fe-C bond homolysis. Here, we describe an unusual way access formally iron(iv) through double silylation of iron(i) dinitrogen form NNSi2 group. Spectroscopically validated computations show that the disilylehydrazido(2-) ligand stabilizes formal oxidation state a strongly covalent Fe-N π-interaction, in which one π-bond fits "inverted field" description. This means two bonding electrons localized more on metal than ligand, and thus...
Iron catalysts are adept at breaking the N–N bond of N 2 , as exemplified by iron‐catalyzed Haber–Bosch process and iron‐containing clusters active sites nitrogenase enzymes. This Minireview summarizes recent work that has identified a well‐characterized set multiiron complexes capable functionalizing amenable to detailed mechanistic studies. We discuss redox balancing, potential intermediates during activation, variation alkali metal reductant, reversibility cleavage, formation N–H N–C bonds from .
Alkynyl complexes of low-coordinate transition metals offer a sterically open environment and interesting bonding opportunities. Here, we explore the capacity iron(I) alkynyl to bind N2 isolate complex including its X-ray crystal structure. Silylation gives an isolable, formally iron(IV) with disilylhydrazido(2−) ligand, but natural bond orbital analysis indicates that iron(II) formulation is preferable. The structure this compound similar earlier reported phenyl in which migration forms new...
Non-aqueous redox flow batteries (NRFB) are of interest due to their enhanced potential for large energy densities compared aqueous batteries. In this work, we compare the effects several commonly used supporting electrolytes on cycling stability our previously reported active organic electrolyte. We report various common cations and anions, combined pairs. find that non-coordinating anions provide most stable battery configurations. Cation will be discussed include...
High-valent iron-alkyl complexes are rare, as they typically prone to Fe–C bond homolysis. We show here an unusual way access formally iron(IV) alkyl through double silylation of iron(I) dinitrogen form NNSi2 group. When the group is trimethylsilylmethyl, compound stable at room temperature. Spectroscopically validated computations that disilylhydrazido(2–) ligand stabilizes formal oxidation state a strongly covalent Fe–N -interaction, in which one -bond fits "inverted field" description....

Alkynyl complexes of low-coordinate transition metals offer a sterically open environment and unusual bonding for reactivity. Here, we explore the capacity iron(I) alkynyl to bind N2, isolate an N2 complex including its X-ray crystal structure. Silylation this gives formally iron(IV) with disilylhydrazido(2–) ligand, but NBO analysis indicates that iron(II) formulation is more accurate. The structure compound similar earlier reported phenyl in which migration forms new N–C bond, group does...
