An N-heterocyclic carbene (NHC) contains a carbene carbon incorporated in a nitrogen-
containing heterocycle, presumably reactive and difficult to isolate. 1 The first isolation of …

Catalytic asymmetric CC bond-forming reactions using organometallic reagents are among
the most important of organic transformations. 1 Frequently, these transformations are key …

Quantification and variation of characteristic properties of different ligand classes is an
exciting and rewarding research field. N‐Heterocyclic carbenes (NHCs) are of special …

A versatile and highly efficient catalyst for the Huisgen cycloaddition reaction has been
developed. Previously isolated or in situ generated azides yielded 1, 2, 3‐triazoles with …

Since the isolation and crystallographic characterization of the first stable N-heterocyclic
carbene in early 1991, 1 nucleophilic diaminocarbenes (also known as “Arduengotype” …

Abstract Die Quantifizierung und Variation der charakteristischen Eigenschaften von
Ligandenklassen ist ein spannendes und lohnenswertes Forschungsgebiet. N …

The preparation of three series of [(NHC) CuX] complexes (NHC= N-heterocyclic carbene,
X= Cl, Br, or I) is reported. These syntheses are high yielding and only use readily available …

The copper-catalyzed asymmetric conjugate addition of Grignard reagents to trisubstituted
cyclic enones affords enantioenriched all-carbon quaternary centers with up to 96% ee. The …

General. All manipulations were carried out in the argon-filled glovebox (Miwa MFG). The 1
H, 1 H {11 B}, 11 B, 11 B {1 H}, and 13 C {1 H} NMR spectra were recorded on 500 MHz …

Silalactone: Die kupferkatalysierte Reaktion interner Alkine mit (Dimethylphenylsilyl)
pinakolboran als Siliciumquelle und mit CO 2 (1 atm) führt selektiv und mit guten Ausbeuten …
