Beginning as chemical curiosities with the pioneering work of Curtius, 1a Staudinger, 1b and
even earlier efforts, 1c carbenes have played an important role as transient intermediates …

The chemistry of heterocyclic carbenes has experienced a rapid development over the last
years. In addition to the imidazolin‐2‐ylidenes, a large number of cyclic diaminocarbenes …

An important role in organometallic chemistry is predicted for N‐heterocyclic carbenes,
which are no longer laboratory curiosites but have developed into an industrially interesting …

N-Heterocyclic carbenes (NHCs) are omnipresent ligands in coordination and
organometallic chemistry, which is reflected by myriads of applications involving NHC …

The latest advances in N-heterocyclic carbene-based organometallic chemistry have drawn
increasing attention to this class of ancillary ligands as an attractive alternative to tertiary …

N-heterocyclic carbenes (NHC) is a well established class of new ligands in organometallic
chemistry. Their use as ligands in many reactions catalyzed by transition metal complexes …

Abstract Die Chemie der heterocyclischen Carbene hat sich in den letzten Jahren stürmisch
entwickelt. Nach den Imidazolin‐2‐ylidenen wurden weitere cyclische Diaminocarbene mit …

Metal NHC complexes have been known for over 50 years, but only during the last 15 have
they been studied as potential catalysts. N-heterocyclic carbene (NHC) complexes are often …

The air-stable crystalline carbene 1, 3-dimesityl-4, 5-dichloroimidazol-2-ylidene (2) is
produced from the chlorination of 1, 3-dimesityimidazol-2-ylidene (1) by 2 equiv of carbon …

The use of N-heterocyclic carbenes as ligands is a rapidly expanding field, and exciting
compounds and catalytic uses are being described for their metal complexes with increasing …
