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 …

Singlet fission (SF) is a photophysical downconversion pathway, in which a singlet excitation
transforms into two triplet excited states. As such, it constitutes an exciton multiplication …

Cyclic (alkyl)-and (aryl)-(amino) carbenes (CAACs and CAArCs) are stronger σ-donors and
π-acceptors than imidazol-2-ylidenes and imidazolidin-2-ylidenes, the well-known N …

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 …

This tutorial explores the diversity and characteristics of C-donor ligands. Particular
emphasis is put on the conceptual design of the electronic properties for applications in …

Discovered in 2005, cyclic (alkyl)(amino) carbenes (CAACs) have led to numerous
discoveries in the field of ruthenium olefin metathesis, until then largely dominated by the …

Since the groundbreaking discovery in 2018 that the synthesis of a bottleable nucleophilic
aluminyl anion is feasible, a handful of derivatives have been developed to date, which are …

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 hydrogenation of alkynes allows the synthesis of olefins, which are important feedstock
for the materials, pharmaceutical, and petrochemical industry. Thus, methods that enable …

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 …
