Victor Grignard Totally Explained

Everything about Victor Grignard totally explained

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 generating carbon-carbon bonds using magnesium to couple ketones and alkyl halides. This reaction is valuable in in organic synthesis. His occurs in two steps:

Formation of the "Grignard reagent," which is an organomagnesium compound made by the reaction an organohalide, R-X (R = alkyl or aryl; and X is a halide, usually bromide or iodide) with magnesium metal. The Grignard reagent is usually described with the general chemical formula R-Mg-X, although its structure is more complex.
Addition of the carbonyl, in which a ketone or an aldehyde is added to the solution containing the Grignard reagent. The carbon atom that's bonded to Mg transfers to the carbonyl carbon atom, and the oxygen of the carbonyl carbon becomes attaches to the magnesium to give an alkoxide. The process is an example of a nucleophilic addition to a carbonyl. After the addition, the reaction mixture is treated with aqueous acid to give an alcohol, and the magnesium salts that are discared.

The Grignard reaction is an important means of preparing organic compounds from smaller precursor molecules. For this work, Grignard was awarded the Nobel Prize in Chemistry in 1912 jointly with fellow Frenchman Paul Sabatier.
