Frenchman, two Americans win 2005 Nobel Prize in Chemistry

The Nobel jury announces that winners of the 2005 Nobel Prize in chemistry

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry for 2005 jointly to Yves Chauvin (Institut Français du Pétrole, Rueil-Malmaison, France), Robert H. Grubbs (California Institute of Technology (Caltech), Pasadena, CA, USA) and Richard R. Schrock (Massachusetts Institute of Technology (MIT), Cambridge, MA, USA) "for the development of the metathesis method in organic synthesis".

Yves Chauvin, 74, Robert Grubbs, 63, and Richard Schrock, 60, will share the $1.3 million, or 10 million kronor prize equally.

The academy said the men's work, begun by Chauvin in 1971, has led to more environmentally friendly applications in advanced plastics and pharmaceuticals, saying atomic manipulation "can be compared to a dance in which the couples change partners."

Metathesis – a change-your-partners dance

This year's Nobel Prize Laureates in chemistry have made metathesis into one of organic chemistry's most important reactions. Fantastic opportunities have been created for producing many new molecules - pharmaceuticals, for example. Imagination will soon be the only limit to what molecules can be built!

Organic substances contain the element carbon. Carbon atoms can form long chains and rings, bind other elements such as hydrogen and oxygen, form double bonds, etc. All life on Earth is based on these carbon compounds, but they can also be produced artificially through organic synthesis.


In 1971 Yves Chauvin was able to explain in detail how metatheses reactions function and what types of metal compound act as catalysts in the reactions. Now the "recipe" was known. The next step was, if possible, to develop the actual catalysts.

Richard Schrock was the first to produce an efficient metal-compound catalyst for methasesis. This was in 1990. Two years later Robert Grubbs developed an even better catalyst, stable in air, that has found many applications.


-- more efficient (fewer reaction steps, fewer resources required, less wastage),
-- simpler to use (stable in air, at normal temperatures and pressures) and
-- environmentally friendlier (non-injurious solvents, less hazardous waste products).

This represents a great step forward for "green chemistry", reducing potentially hazardous waste through smarter production. Metathesis is an example of how important basic science has been applied for the benefit of man, society and the environment.
