Century-Old Chemistry Problem Solved
====================================
In this week’s issue of Science, an article entitled The Catalytic
Cross-Coupling of Unactivated Arenes will be published by Dave Stuart,
uOttawa PhD student, along with his supervisor Dr. Keith Fagnou, both
from the Department of Chemistry.

The researchers have found a solution to a problem that is more than
100 years old—how to couple two unactivated carbon atoms together with
the help of a catalyst.

The molecules formed – called biaryl molecules – are the building
blocks of light emitting diodes (LEDs), electron transport devices and
liquid crystals found in modern LCD screens, and are found in
approximately one in 20 medicines on the market today, such as
Vancomycin, a last resort antibiotic and Glivec, an anti-cancer agent.
Stuart’s solution will allow chemists to create biaryl molecules in a
much more environmentally-friendly way and reduce costs significantly.

Stuart’s work was described as “one of the most important discoveries
in this field” and it will “be used as a flagship for this fundamental
area of chemical science.”

Note: This story has been adapted from a news release issued by
University Of Ottawa.
