Following a strong regain of interest over the past 20 years in the chemistry of allenes, this
“forgotten” family of unsaturated molecules is undergoing a renaissance. In this context, the …

This review considers phosphine and N-heterocyclic carbene complexes of gold (I) that are
used as (pre) catalysts for a range of reactions in organic synthesis. These are divided …

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 …

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 …

This Review examines recent developments in late transition metal-catalyzed
hydroamination and-amidation reactions. A hydroamination is a reaction in which an N− H …

Titanium is the second most abundant transition metal and is already a key player in
important industrial processes (eg polyethylene). Titanium is an attractive metal to use for …

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 …

In this critical review the reactivity patterns observed with different types of diyne substrates
in gold catalysis are discussed. Apart from the many examples from homogeneous catalysis …

N-Heterocyclic carbenes (NHCs) are cyclic carbenes bearing at least one R-amino
substituent. 1 The most common subclasses of NHCs are represented in Chart 1. Early work …
