Radical species are significant in modern chemistry. Their unique chemical bonding and
novel physicochemical properties play significant roles not only in fundamental chemistry …

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 …

Activation of inert molecules like CO2 is often mediated by cooperative chemistry between
two reactive sites within a catalytic assembly, the most common form of which is Lewis …

Isolation and characterization of stable radicals has been a long-pursued quest. While there
has been some progress in this field particularly with respect to carbon, radicals involving …

Over the past decade, numerous stable organic and main‐group radicals have been
synthesized from N‐heterocyclic carbenes (NHCs). The structure of NHCs, in particular …

Aluminum (III) is inherently electron deficient and therefore acts as a prototypical Lewis acid.
Conversely, Al (I) is a rare, nucleophilic variant of aluminum that is thermodynamically …

A non‐solvated alkyl‐substituted Al (I) anion dimer was synthesized by a reduction of
haloalumane precursor using a mechanochemical method. The crystallographic and …

Electrophilic AlIII species have long dominated the aluminum reactivity towards arenes.
Recently, nucleophilic low‐valent AlI aluminyl anions have showcased oxidative additions …

The synthesis and characterization of isolable radicals of main-group elements have been a
long-pursued quest. Although there has been considerable progress in this area, particularly …

The first examples of cyclic (alkyl)(amino) carbene (CAAC) lanthanide (Ln) complexes were
synthesized from the reaction of CAAC with Yb [N (SiMe3) 2] 2 and Eu [N (SiMe3) 2] 2 (THF) …
