François Auguste Victor Grignard Biography
- Nobel Prize Winner (1912)
François Auguste Victor Grignard
(May 6, 1871 in Cherbourg - December 13, 1935 in Lyon) was a Nobel Prize-winning
French chemist.
Grignard was the son of a sail maker. After studying mathematics at Lyon he
transferred to chemistry, becoming a professor at the University of Nancy in
1910. During World War I, he was transferred to the new field of chemical
warfare, and worked on the manufacture of phosgene and the detection of mustard
gas. His "opposite number" on the German side was another Nobel Prize winning
Chemist, Fritz Haber.
He is most noted for devising a new method for creating carbon-carbon bonds (i.e.
an addition reaction) in organic synthesis (Original publication: V. Grignard,
Compt. Rend. Vol. 130, p. 1322 (1900)). The synthesis occurs in two steps:
1.Synthesis of the Grignard reagent: an organomagnesium compound (the Grignard
reagent) is made reacting an organohalide (R-X, where R stands for some alkyl,
acyl, or aryl radical and X is a halogen such as usually bromine or iodine) with
magnesium metal dissolved in diethyl ether. The resulting compound, named a
Grignard reagent, has the general chemical formula R-Mg-X.
2.Attack on the carbonyl: A ketone or an aldehyde (both contain a carbonyl group)
is added to the solution containing the Grignard reagent. The carbon atom that
is bonded to the Mg atom bonds to the carbonyl carbon atom by nucleophilic
addition, with the formation of a new compound, which is an alcohol.
The Grignard reaction is an important means of making larger organic compounds
from smaller starting materials. By careful selection of the starting materials,
a wide variety of compounds can be made by this reaction. For this work,
Grignard was awarded the Nobel Prize in Chemistry in 1912 jointly with fellow
Frenchman Paul Sabatier (chemist).
