The success of homogeneous catalysis can be attributed largely to the development of a
diverse range of ligand frameworks that have been used to tune the behavior of various …

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 …

Under an atmosphere of carbon monoxide (CO), a (phosphino) diazomethyl anion salt [[P]‐
CN2][K (18‐C‐6)(THF)](1)([P]=[(CH2)(NDipp)] 2P; 18‐C‐6= 18‐crown‐6; Dipp= 2, 6 …

Until recently, the availability of neutral carbon-based κ 1 C ligands was limited to carbon
monoxide, isocyanides, and carbenes. Compared to phosphorus-based ligands, carbenes …

Semantics, definitions? The description of the electronic structure of main‐group compounds
with dative bonds significantly enriched the chemistry of sp block elements. The new …

Carbophilic Lewis acids can polarize a coordinated π-bond by a slippage mechanism. A
series of stable ylid-or enolate gold complexes of ene-1, 1-diamines not only emulate this …

Quantum‐chemical calculations with DFT (BP86) and ab initio methods [MP2, SCS‐MP2,
CCSD (T)] have been carried out for the molecules C (PH3) 2 (1), C (PMe3) 2 (2), C (PPh3) …

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 …

Abstract Der Erfolg der homogenen Katalyse kann hauptsächlich der Entwicklung einer
breiten Palette von Ligandengerüsten zugeschrieben werden, die vielfach genutzt wurden …
