Extractions: Grignard's first investigations concerned "ethyl b -isopropylacetobutyrate and the stereoisomeric diisopropylbutenedicarboxylic acids" and studies of branched unsaturated hydrocarbons. In 1899, on Barbier's recommendation, he studied organomagnesium compounds and his discovery of the classic preparation of magnesium alkyl halides was first communicated by Henri Moissan Grignard was the author of some 170 publications on his researches and, at his death, he was working to fulfil his ambition to see a great chemical reference work in the French language. Two volumes of his (Treatise on organic chemistry) had already been published, two more were ready for the press and the editorial work for another two was well advanced: it was later to be finished by his collaborators. In 1937, two of his students, Jean Cologne and Roger Grignard, published (Survey of organic chemistry) which is based on Grignard's lecture course in organic chemistry.

Francois Auguste victor grignard. French chemist, nobel Prizewinner in 1912 forgrignard reagents Born Cherbourg, 6 May 1871 Died Lyon, 13 December, 1935.
http://www.sunderland.ac.uk/~hs0bcl/h_vg.htm

Extractions: Died: Lyon, 13 December, 1935 Victor Grignard had a strange start in academic life for a chemist - he took a maths degree. When he eventually switched to chemistry, it wasn't to the mathematical province of physical chemistry but to organic chemistry. While attempting to find an efficient catalyst for the process of methylation, he noted that Zn in diethyl ether had been used for this purpose and wondered whether the Mg/ether combination might be successful. Grignard reagents were first reported in 1900 and Grignard used this work for his doctoral thesis in 1901. In 1910, Grignard obtained a professorship at the University of Nancy and in 1912 was awarded the Nobel prize for chemistry which he shared with Paul Sabatier who had made advances in Nickel catalysed hydrogenation.

http://www.sunderland.ac.uk/~hs0bcl/org3.htm

Extractions: How to Tackle Organic Syntheses - a Beginner's Guide by Prof Otto Meth-Cohn The Grignard Reaction Victor Grignard was an enthusiastic young French chemist who discovered how to make organomagnesium halides (RMgX) while working for his PH.D. His boss, Barbier, had been trying this sort of chemistry for some time, but Victor was the genius who solved the problem. This discovery in 1901 changed the course of organic chemistry and won him the Nobel Prize in 1912. We now refer to such compounds as Grignard Reagents - and they are the first tool in your bag. Victor's breakthrough came with two discoveries - an ether solvent was vital and the whole chemistry must be carried out bone dry . You take an alkyl halide (preferably a bromide or iodide but a very reactive chloride such as tertiary-butyl chloride or benzyl chloride will be OK) magnesium metal and ether (dried with sodium metal) and with a little persuasion you get a vigorous reaction resulting in a Grignard reagent. The reagent is used in solution (it is soluble in ether) and is never isolated. The metal is positively polarised and the alkyl group thus is like a carbanion. It certainly behaves as a carbanion. All kinds of alkyl halides react - and amazingly, even bromobenzene and other aryl bromides and iodides react easily with magnesium. This is particularly surprising since the aromatic halogen is so unreactive. For example, it is inert to refluxing aqueous sodium hydroxide even above 200C.

http://www.britannica.com/nobel/micro/247_60.html

Extractions: Victor Grignard, print Library of Congress/Corbis Paul Sabatier , of the Nobel Prize for Chemistry in 1912 for his development of the Grignard reaction. This work in organomagnesium compounds opened a broad area of organic synthesis. In 1898, while a student under Philippe Barbier at Lyon, Grignard began his prizewinning work with a study of the alkylzinc compounds developed earlier by Sir Edward Frankland. It was Barbier who had Grignard repeat some experiments on the preparation of a tertiary alcohol from a mixture of methyl heptyl ketone, magnesium, and methyl iodide. Grignard hit upon the idea of treating the iodide with the magnesium first and carried out the reaction in ether. This first of the Grignard reagents was a complete success. Grignard's doctoral dissertation (1901) described the preparation of alcohols, acids, and hydrocarbons by means of reactions of organomagnesium compounds. He became professor of chemistry at Nancy (1910) and at Lyon (1919). At the time of his death some 6,000 papers reporting applications of the Grignard reaction had been published.

Extractions: Pronunciation Key Grignard reagent , any of an important class of extremely reactive chemical compounds used in the synthesis of hydrocarbons, alcohols, carboxylic acids, and other compounds. Chemically, a Grignard reagent is an organic magnesium halide dissolved in a nonreactive solvent (typically dry ethyl ether). The substance is made up of an organic group, e.g., an alkyl or aryl group, joined by a highly polar covalent bond (see chemical bond ) to magnesium, while the magnesium is joined by an ionic bond to a halogen ion, e.g., bromide or iodide. A Grignard reagent will react with water, oxygen, carbon dioxide, or almost any electrophilic organic compound. The reaction of Grignard reagents with aldehydes to form alcohols is of particular importance in the laboratory. Because Grignard reagents are so unstable, they are generally prepared just before use by reacting an organic halide, e.g., methyl iodide, with magnesium metal in a completely dry solvent; air is usually excluded from the reaction vessel, e.g., by flushing it with nitrogen. Grignard reagents are named after Victor

Extractions: Victor Grignard Victor Grignard, prix Nobel à 41 ans, fait partie des grands chimistes français qui ont laissé leur nom dans l'histoire. C'est en effet le seul qui figure dans tous les ouvrages de chimie organique, du plus simple au plus complexe, pour avoir mis au point les organomagnésiens, une classe de molécules particulièrement utilisées en synthèse organique. Sa vie En 1894, il prépare une licence de sciences-physiques à la faculté des sciences de Lyon. Il obtient un modeste poste de préparateur dans le laboratoire de chimie de Philippe Barbier, personnage imposant et autoritaire. Barbier était un des précurseur à utiliser les organométalliques comme composés particulièrements réactifs, tels les organozinciques voire les organomagnésiens. C'est dans ce laboratoire que Grignard va mettre au point les organomagnésiens. Il publiera d'ailleurs en 1900, un article dans les comptes rendus de l'académie des sciences : " Sur quelques nouvelles combinaisons organométalliques du magnésium et leur application à la synthèse d'alcools et d'hydrocarbures ". On dénombrera en 1906 près de 350 publications faisant référence aux réactifs de Grignard, et près de 700 en 1910, ce qui reste important encore aujourd'hui mais qui était énorme pour l'époque. En 1901, il présente une thèse remarquée sur les organomixtes. Il travaille un temps à la faculté des sciences de Besançon mais reviendra à Lyon comme maître de conférence.
