Since the discovery of the first stable N-heterocyclic carbene (NHC) in the beginning of the
1990s, these divalent carbon species have become a common and available class of …

N-Heterocyclic carbenes (NHC) are nowadays ubiquitous and indispensable in many
research fields, and it is not possible to imagine modern transition metal and main group …

Since the latter quarter of the twentieth century, main group chemistry has undergone
significant advances. Power's timely review in 2010 highlighted the inherent differences …

The focus of this review is the presentation of the most important aspects of chemical
bonding in molecules of the main group atoms according to the current state of knowledge …

A complex of a metal in its zero oxidation state can be considered a stabilized, but highly
reactive, form of a single metal atom. Such complexes are common for the more noble …

Conspectus Silylenes are divalent silicon species with an unoccupied 3p orbital and one
lone pair of electrons at the SiII center. Owing to the excellent σ-donating ability of amidinato …

Carbenes have evolved from transient laboratory curiosities to a robust, diverse, and
surprisingly impactful ligand class. A variety of different carbenes have significantly …

Carbenes are perhaps the most versatile reactive intermediates in chemistry. Since the
original visions of “methylene” by Dumas 1 in 1835 and a generalization of this vision by Nef …

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 …

Since the first report of their isolation in 2007, magnesium (i) dimers have transitioned from
being chemical curiosities to versatile reducing agents that are used by an ever-increasing …
