The basicities of simple organic bases–aliphatic and aromatic amines, amidines,
phosphazenes, as well as saturated and unsaturated nitrogen heterocycles–are examined …

N-Heterocyclic carbenes (NHCs) are cyclic carbenes bearing at least one R-amino
substituent. 1 The most common subclasses of NHCs are represented in Chart 1. Early work …

Iron is the most abundant transition metal in Earth, s crust; it is relatively inexpensive, not
very toxic, and environmentally benign. 1 Undoubtedly, due to the involvement in a multitude …

Dipyrromethene ligand scaffolds were synthesized bearing large aryl (2, 4, 6-Ph3C6H2,
abbreviated Ar) or alkyl (t Bu, adamantyl) flanking groups to afford three new disubstituted …

High-oxidation-state 3d metal species have found a wide range of applications in modern
synthetic chemistry and materials science. They are also implicated as key reactive species …

Enzymes are highly efficient catalysts in Nature that often react with high stereo-, chemo-,
and regioselectivity. Usually, enzymes achieve this selectivity through substrate binding and …

The electronic structure, spectroscopic features, and (catalytic) reactivity of complexes with
nitrogen‐centered radical ligands are described. Complexes with aminyl ([M (. NR2)]) …

N-Heterocyclic carbenes (NHCs) are nowadays ubiquitous and indispensable as ancillary
ligands in organotransition metal chemistry, with an enormous variety of NHC types known …

We present a family of trigonal pyramidal iron (II) complexes supported by tris (pyrrolyl-α-
methyl) amine ligands of the general formula [M (solv) n][(tpaR) Fe](M= Na, R= tert-butyl (1) …

The equilibrium acidity scale (pKa scale) in acetonitrile has been supplemented by
numerous new compounds and new ΔpKa measurements. It now contains altogether 231 …
