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 …

Abstract Free borylenes (R–B:) have only been spectroscopically characterized in the gas
phase or in matrices at very low temperatures. However, in recent years, a few mono‐and …

Cyclic (alkyl)(amino) carbenes with a six-membered backbone were prepared. Compared to
their five-membered analogues, they feature increased% V bur and enhanced donor and …

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

Isolation of cyclic (alkyl) amino carbenes (cAACs) in 2005 has been a major achievement in
the field of stable carbenes due to their better electronic properties. cAACs and bicyclic …

A straightforward strategy allows for the synthesis of storable bicyclic (alkyl)(amino)
carbenes (BICAACs), which feature enhanced σ-donating and π-accepting properties …

An investigation of carbodicarbenes, the less explored member of the carbenic
complex/ligand family has yielded unexpected electronic features and concomitant …

Reduction of alkynyl iminium salts derived from cyclic (alkyl)(amino) carbenes (CAACs)
affords propargyl/allenyl radicals. Depending on the nature of the CAAC and alkyne …

First examples of anionic cyclic (alkyl)(amino) carbenes (Ani‐cAACs) that contain borane
substituents have been synthesized. The nature of the borane substituents allows a …
