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 …

Abstract Discovered in 2005, cyclic (alkyl)(amino) carbenes (CAACs) are among the most
nucleophilic (σ donating) and also electrophilic (π‐accepting) stable carbenes known to …

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 …

The progress in experimental and theoretical research in the area of main group compounds
that possess dative bonds, which was made in the last decade, is summarized. The focus …

Ein Kennzeichen der seit 2005 bekannten cyclischen Alkylaminocarbene (CAACs) ist ihre
ausgeprägte Nucleophilie (σ‐Donor) und zugleich Elektrophile (π‐Akzeptor). Diese …

A summary of theoretical and experimental work in the area of low-coordinated compounds
of boron and group-14 atoms C–Sn in the last decade is presented. The focus of the account …

Over decades diazoalkenes (R2C= C= N2) were postulated as reactive intermediates in
organic chemistry even though their direct spectroscopic detection proved very challenging …

Homometallic copper complexes with alkenylidene ligands are discussed as intermediates
in catalysis but the isolation of such complexes has remained elusive. Herein, we report the …

A modular approach for the synthesis of Kekulé diradicaloids is reported. The key step is the
insertion of a carbene, namely, a cyclic (alkyl)(amino) carbene (CAAC), into the C–H bonds …

Organic singlet diradicaloids promise application in non-linear optics, electronic devices and
singlet fission. The stabilization of carbon allotropes/cumulenes (C1, C2, C4) by carbenes …
