The chemistry of heterocyclic carbenes has experienced a rapid development over the last
years. In addition to the imidazolin‐2‐ylidenes, a large number of cyclic diaminocarbenes …

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 …

Oxidative addition and reductive elimination are key steps in a wide variety of catalytic
reactions mediated by transition-metal complexes. Historically, this reactivity has been …

Conspectus Carbenes are compounds that feature a divalent carbon atom with only six
electrons in its valence shell. In the singlet state, they possess a lone pair of electrons and a …

The success of homogeneous catalysis can be attributed largely to the development of a
diverse range of ligand frameworks that have been used to tune the behavior of various …

The organometallic chemistry of N-heterocyclic carbenes (NHCs) has experienced
explosive development during the last few years, and the topic remains the main focus of …

Organic π-conjugated polymers and oligomers (Chart 1) are intriguing compounds that have
been intensively studied for almost 30 years by now. 1-3 The interest in these systems is …

This personal account summarizes our work, beginning with the discovery of the first stable
carbene in 1988 up until the recent isolation of mesoionic carbenes. It explains why we have …

The [3+ 2] cycloaddition of azides and acetylenes followed by nitrogen quaternization was
applied for the generation of novel and highly modular triazolium salts. The selective …

Carbenes are neutral compounds featuring a divalent carbon atom. Their rich reactivity both
as naked species and within complexes of transition metals has allowed for spectacular …
