Self-assembly of N-heterocyclic carbenes on Au(111)

Nature Communications, 2021
Although N-heterocyclic carbenes (NHCs) are a promising class of ligands for forming robust self-assembled monolayers on metals, many questions remain about their behavior on surfaces.

A persistent P,N-heterocyclic carbene [PDF]

Chemical Communications, 2008
Conjugate acids of cyclic (amino)(phosphino)carbenes (P-NHCs) have been prepared, and several different processes have been observed during their deprotonation, which include the formation of a metastable P-NHC, an azomethine ylide, and a bicyclic phosphirane.

Direct estimate of the internal π-donation to the carbene centre within N-heterocyclic carbenes and related molecules

Beilstein Journal of Organic Chemistry, 2015
Fifteen cyclic and acylic carbenes have been calculated with density functional theory at the BP86/def2-TZVPP level. The strength of the internal X→p(π) π-donation of heteroatoms and carbon which are bonded to the C(II) atom is estimated with the help of

N-Heterocyclic carbene-catalyzed oxidations [PDF]

Tetrahedron, 2009
N-Heterocyclic carbenes catalyze the oxidation of allylic and benzylic alcohols as well as saturated aldehydes to esters with manganese(IV) oxide in excellent yields. A variety of esters can be synthesized, including protected carboxylates. The oxidation proceeds under mild conditions, with low loadings of a simple triazolium salt pre-catalyst in the ...
