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 …

In the past decades there has been a dramatic increase in the demand for enantiopure
compounds for fine-chemicals (ie, agrochemicals and pharmaceuticals) and material …

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

The strong σ-donor but poor π-acceptor abilities of N-heterocyclic carbenes (NHCs) result in
chemical stability and coordination versatility, thus allowing them to coordinate with many …

Although the chemistry of copper has a long history [1a-d], the relatively recent discovery of
N-heterocyclic carbene (NHC) as transition-metal supporting ligands has permitted novel …

A new chiral bidentate N-heterocyclic carbene (NHC) ligand has been designed and
synthesized. The NHC ligand bears a chiral diamine backbone and an achiral biphenol …

Single enantiomers of chiral amines are starting materials for N-heterocyclic carbenes
(NHC),[1] and these NHCs have found very significant applications in asymmetric …

We present a 6-NHC− Cu (I) complex that provides α-substituted allylboronates using allylic
aryl ether substrates. The method was discovered by comparison of the chemoselectivities …

An efficient method for catalytic asymmetric allylic alkylation (AAA) of allylic phosphates with
vinylaluminum reagents is reported. The vinylmetal reagents are prepared by reaction of …
