 Why
do you think your paper is highly cited?
|
“This paper collects the information on the synthesis of
Ag(I) N-heterocyclic carbenes (NHCs)...”
|
|
N-heterocyclic carbenes (NHCs) are new, versatile, and very
useful ligands in organometallic chemistry and catalysis. This
paper collects the information on the synthesis of Ag(I)
N-heterocyclic carbenes, which can be readily prepared and used
in order to prepare other potentially very useful transition
metal-carbenes.
Does
it describe a new discovery, methodology, or synthesis of
knowledge?
It is a new and easy methodology based on our previous report
(Organometallics, Vol.17, 972, 1998), where the Ag(I)
NHCs formed by the reaction of Ag2O with an
imidazolium salt were used as carbene group transfer agents to
produce metal-NHCs effectively.
Could
you summarize the significance of your paper in layman's terms?
This paper provides a comprehensive documentation of an
important class of silver compounds, which can be easily
prepared under ambient conditions. Moreover, the accomplishment
of this reaction can be watched with the naked eye.
How
did you become involved in this research, and were any problems
encountered along the way?
The development of this result was not on purpose. While in
an attempt to synthesize Au(I)-NHCs using
different bases for the deprotonation of azolium salts, the
employment of Ag2O as a mild base produced the
Au(I)-NHCs effectively. This study implied the generation of
Ag(I)-NHCs in situ, and their role as transmetallating
agents to prepare other metal-NHCs.
