The emergence of N-heterocyclic carbenes as ligands across the Periodic Table had an
impact on various aspects of the coordination, organometallic, and catalytic chemistry of the …

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 …

Shortly after their discovery at the end of the 80s, stable singlet carbenes have been
recognized as excellent ligands for transition metal based catalysts, and as organo-catalysts …

The continuous growth of N-heterocyclic carbene (NHC) chemistry is a fact that is pointed
out in all the introductions of the publications regarding NHCs that have appeared in the …

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 …

The coordination and organometallic chemistry of linear, rigid, tridentate ligands, which
incorporate at least one N-heterocyclic carbene and other 'classical'donors, is reviewed …

N-heterocyclic carbenes are compared with cyclopentadienyls and phosphines in terms of
bonding and reactivity. Synthetic difficulties that currently prevent the general incorporation …

There are mechanistic dichotomies with regard to the formation, electronic structures and
reaction mechanisms of metal–oxygen intermediates, since these metal–oxygen species …

The use of polydentate NHC ligands has allowed the preparation of new compounds whose
stability is entropically improved by the chelate effect. Chelate-N-heterocyclic ligands also …

N-Heterocyclic carbene (NHC) ligands are attracting worldwide interest because of their
considerable scope and potential in coordination/organometallic chemistry, catalysis and …
