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.
The researchers in Singapore produced the
carbene catalyst used in the reaction in situ from a precursor.
We have recently synthesized a ruthenium
carbene complex which is a reversibly water-soluble, pH-responsive catalyst which has potential for improved catalyst separation and recycling.

CARBENE LIGANDS.
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.

DEVELOPMENT OF NOVEL CHELATING N-HETEROCYCLIC
CARBENE LIGANDS.
Isocyanide, or isonitrile, chemistry attracted much attention at the end of the 20th century when the stable
carbene began being used for diversity-oriented synthesis, high throughput screening, and drug discovery.
Presentations were given on mechanistic organometallic chemistry with silicon-containing compounds (Jennifer Love, MCIC, UBC), mass spectrometry techniques for catalyst discovery and reaction optimization (Scott McIndoe, MCIC, University of Victoria) and new main-group ring systems with
carbene character (Roland Roesler, MCIC, University of Calgary).
