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 …

This review article provides a survey of contemporary investigations on main group metal
cluster formation, addressing homo‐and heterometallic clusters (including small numbers of …

We analyze the key transition metal ligand properties, σ-donor and π-acceptor ability, ligand-
to-metal charge transfer, and steric parameters, using theoretical methods in order to …

The recent progress in the synthesis of partially substituted neutral silicon clusters
(siliconoids) revealed unique structures and electronic anisotropies that are reminiscent of …

Transition-metal complexes of cyclopropenes occur as fleeting intermediates of numerous
metal-catalyzed organic transformations. A heavier analogue has now been obtained from …

The reaction of PhC (NtBu) 2SiSi (SiMe3) 3 (1) with Me3SiCH2Cl afforded an unsymmetrical
sp2–sp3 disilene, 2, with concomitant elimination of Me3SiCl. The analogous reaction with …

The reaction of the bulky diphosphenes (Rind) P= P (Rind)(1; Rind= 1, 1, 3, 3, 5, 5, 7, 7‐octa‐
R‐substituted s‐hydrindacen‐4‐yl) with two molecules of N‐heterocyclic carbene (NHC; 1 …

The mixed heteroadamantanes Si6Ge4 and Si6Sn4 are readily accessible from
Me2ECl2/Si2Cl6/cat. Cl−(4× EMe2, 2× SiCl2, 4× Si–SiCl3 vertices; E= Ge, Sn). Different …

The two-electron reduction of the dismutational isomer of a 1, 4-digermatetrasilabenzene
cleaves one of the aryl groups in ligato-position and thus yields an unsaturated anionic …

Small unsaturated phosphacycles are versatile reagents owing to their strain and the added
functionality of the double bond and the phosphorus lone pair. Herein we report the …
