    Extractions: Chemikalien-Lexikon: Namensreaktionen G RIGNARD -Reagenzien (1901) Victor G RIGNARD (1871-1935), geboren in Cherbourg (Frankreich), arbeitete als Professor der Chemie an den Universitäten von Nancy und Lyon. Die Gewinnung von magnesiumorganischen Verbindungen nach G RIGNARD führt zu präparativ ausgesprochen nützlichen Reagenzien. Diese zählen zu den am frühesten bekannten metallorganischen Reagenzien überhaupt. Bereits um die Jahrhundertwende arbeiteten die Forscher B ARBIER und G RIGNARD an entsprechenden Darstellungsmethoden und Umsetzungen. Für sein Werk erhielt letzterer den Nobelpreis (1912). Bahnbrechend war dabei die Entdeckung, daß die Lösung eines Alkyl- oder auch Arylhalogenids (Alk-X, Ar-X, allgemein formuliert R-X oder R-Hal ) in wasser- und alkoholfreiem Diethylether in der Lage ist, metallisches Magnesium allmählich aufzulösen! Dabei "schiebt" sich das Magnesium in die Bindung zwischen Kohlenstoff und Halogen ein, und es entsteht ein G RIGNARD -Reagenz: Neben Diethylether sind auch "höhere" oder zyklische Ether (wie Dibutylether, Anisol oder Tetrahydrofuran) und andere nukleophile Lösungsmittel geeignet. Wichtig ist allerdings, daß kein aktiver Wasserstoff vorhanden ist. Zwar tritt in obigem Reaktionsschema das Lösungsmittel nicht als Teil des G RIGNARD -Reagenz' in Erscheinung, doch spielt es bei dessen Entstehung und

    Extractions: Nobel Prize Winning Chemists Victor Grignard The Nobel Prize In Chemistry 1912 Francois Auguste Victor Grignard was born in Cherbourg on May 6, 1871. In 1901 he submitted his brilliant thesis on organic magnesium compounds Sur Les Combinaisons organomagnesiennes mixtes , and was awarded the degree Docteur es Sciences de Lyons. Grignard's first investigations concerned "ethyl beta-isopropylacetobutyrate and the stereoisomeric dilsopropylbutenedicarboxylic acids" and studies of branched unsaturated hydrocarbons. He studied organomagnesium compounds and his discovery of the classic preparation of magnesium alkyl halides was first communicated by Henri Moissan to the Academie des Sciences on May 11, 1900. He quickly developed the immediate applications of these elegant and simple reagents, which were destined to play such an important part in organic synthesis that, at the time of his death in 1935, there were over 6,000 references to them in the literature. He used the agents to prepare and study the more exotic alcohols, ketones, keto-esters, nitriles and terpene compounds and he developed a method for the synthesis of fulvenes. Grignard shared the Cahours Prize in 1901 and again in 1902, when he also won the Berthelot Medal. In 1905 he was awarded the Prix Jecker and in 1912 the Lavoiser Medal. In 1912 the Nobel Proze for Chemistry was conferred upon him, on account of his discovery of the so called Grignard reagent, sharing the prize with Paul Sabatier who received it because of his method of hydrogenating organic compounds by means of finely divided metals.

    Extractions: Grignard Reagents So far, we have built a small repertoire of reactions that can be used to convert one functional group to another. We have briefly discussed converting alkenes to alkanes; alkanes to alkyl halides; alkyl halides to alcohols; alcohols to ethers, aldehydes, or ketones; and aldehydes to carboxylic acids. We have also shown how carboxylic acids can be converted into esters and amides. We have yet to encounter a reaction, however, that addresses a basic question: How do we make C C bonds? One answer resulted from the work that Francois Auguste Victor Grignard started as part of his Ph.D. research at the turn of the century. Grignard noted that alkyl halides react with magnesium metal in diethyl ether (Et O) to form compounds that contain a metal-carbon bond. Methyl bromide, for example, forms methylmagnesium bromide. Et O CH Br + Mg CH MgBr Because carbon is considerably more electronegative than magnesium, the metal-carbon bond in this compound has a significant amount of ionic character. Grignard reagents such as CH MgBr are best thought of as hybrids of ionic and covalent Lewis structures.
