Coordination-induced bond weakening is a phenomenon wherein ligand X–H bond
homolysis occurs in concert with the energetically favorable oxidation of a coordinating …

Living systems carry out the reduction of N2 to ammonia (NH3) through a series of
protonation and electron transfer steps under ambient conditions using the enzyme …

Highly reactive organometallic species that mediate reductive proton-coupled electron
transfer (PCET) reactions are an exciting area for development in catalysis, where a key …

A series of structurally well-defined iron–dinitrogen complexes (L Fe–N2) bearing
cyclopentadienyl-phosphine ligands (L) were synthesized and analyzed by single-crystal X …

The use of cyclopentadienyl ligands in organometallic chemistry and catalysis is ubiquitous,
mostly due to their robust spectator role. Nonetheless, increasing examples of non‐innocent …

Using the doubly protic bis-pyrazole-pyridine ligand (N (NNH) 2), we have synthesized an
octahedral IrIII–H [HIr (κ3-N (NNH)(NN–))(CO)(t BuPy)]+([1-MH]+) from an IrI starting …

A series of low-valent square-planar Rh complexes [LH Rh][X](X= PF6, Br, Cl, I) bearing two
protic imidazolyl phosphines (one κ2) and a CO ligand were synthesized and fully …

Studying the redox behavior of Earth-abundant metal complexes and understanding their
reactivity under reducing conditions is of fundamental importance for activating small …

In hydrogenation mediated by half-sandwich complexes of Rh, Cp* Rh (III)–H intermediates
are critical hydride-delivery agents. For bipyridine-supported complexes, a unique …

Binding of N2 by the FeMo-cofactor of nitrogenase is believed to occur after transfer of 4 e–
and 4 H+ equivalents to the active site. Although pulse EPR studies indicate the presence of …
