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 …

Recent theoretical studies are reviewed which show that the naked group 14 atoms E= C–
Pb in the singlet 1D state behave as bidentate Lewis acids that strongly bind two σ donor …

The progress in experimental and theoretical research in the area of main group compounds
that possess dative bonds, which was made in the last decade, is summarized. The focus …

There is a continuing increase in interest regarding the synthesis and reactivity of low-valent
silicon species. Besides the successful access to two-coordinate cyclic [1] and acyclic …

Silicon, the congener of carbon, frequently shows different chemistry than that of its sister
element. It has been realized that silicon prefers a positive charge if bonded to a more …

By employing the chelate dicarbene 1, the new chlorogermyliumylidene complex 2 could be
synthesized and isolated in 95% yield. Dechlorination of 2 with sodium naphthalenide …

The cyclic alkyl (amino) carbene (cAAC:)-stabilized acyclic germylones (Me2-cAAC:) 2Ge (1)
and (Cy2-cAAC:) 2Ge (2) were prepared utilizing a one-pot synthesis of GeCl2 (dioxane) …

Complexes that could be switched between two electronic states by external stimuli have
attracted much attention for their potential application in molecular devices. However, a …

An experimental and theoretical charge density study confirms the interpretation of (cAAC)
2Si as a silylone to be valid. Two separated VSCCs present in the non‐bonding region of …

Quantum chemical calculations have been carried out to study the electronic structure of
metalated ylides particularly in comparison to their neutral analogues, the bisylides. A series …
