We weren't the first people who looked at heterocyclic
carbenes as ligands," he says, "but we and a number of other people started to look at them at a very fundamental level.
In 1991, Arduengo reported the first stable crystalline
carbene.
The basic framework of an N-heterocyclic
carbene is a five-membered ring made of two nitrogen and three carbon atoms.
As reported in the journal Angewandte Chemie, the scheme is based on an N-heterocyclic
carbene catalyst and a silane as the reducing agent.
Our research targets the synthesis of novel Ru-based metathesis catalysts which bear functionalized
carbene moieties 2-5 which should enhance catalyst solubility in aqueous solvents for application in Ring Opening Metathesis Polymerization (ROMP) of water-soluble norbornene derivatives (Figure 1).
The metathesis catalysts are transition metal
carbene catalysts.
Cowley (to whom the volume is dedicated) opens the volume with a review of his recent work in the area of
carbene analogs.
Alternatively, related pincer-Pd complexes based on supporting N-heterocyclic
carbene (NHC) ligands have been shown to behave as molecular catalysts.
Physical organic chemistry of transition metal
carbene complexes.
Arrey's research interests include: (1) Chemical Education--Organic Chemistry and Methods of Learning and Teaching, (2) Synthesis, Characterization, Computational, and Reactivity of heterocyclic
Carbene, Diazirine and Nitrene molecules.
A
carbene contains a central carbon atom with two bonds, rather than carbon's typical four.
