N‐Heterocyclic Carbenes [PDF]

European Journal of Inorganic Chemistry, 2009
The N-heterocyclic carbenes (NHC) now hold a preferred-ligand status in organic and organometallic chemistry. Their role in catalysis continues to grow. When the editorial staff at the Beilstein Journal of Organic Chemistry contacted me to act as a guest editor for the thematic series “N-Heterocyclic carbenes”, I was more than happy to accept what ...

Nickel N-Heterocyclic Carbene Catalysts for Ester Carbonylation

, 2022
Millions of tons of “acetyls” such as acetic acid and acetic anhydride are produced each year. These basic building blocks of chemical industry are elaborated into esters, amides, and eventually polymer materials, pharmaceuticals, and other consumer ...

Enhancing Interfacial Charge Transport in Gold Nanoparticle@Polyaniline Hybrids via N-Heterocyclic Carbene Linkers. [PDF]

Angew Chem Int Ed Engl
An amino‐functionalized NHC‐Au complex is employed as a conductive molecular linker to couple large Au NPs with PANI, yielding Au NP@NHC‐PANI hybrids with an electronically well‐defined interface. SAMs of these hybrids reveal enhanced charge transport compared with Au NP@PANI.

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.
