    Extractions: German chemist whose method of synthesizing olefins (alkenes) from carbonyl compounds is a reaction often termed the Wittig synthesis. For this achievement he shared the 1979 Nobel Prize for Chemistry. Wittig was born in Berlin and studied at Kassel and Marburg. He was professor at Freiburg 1937-44, Tubingen 1944-56, and Heidelberg 1956-67. In the Wittig reaction, which he first demonstrated 1954, a carbonyl compound (aldehyde or ketone) reacts with an organic phosphorus compound, an alkylidenetriphenylphosphorane, (C6H5)3P=CR2, where R is a hydrogen atom or an organic radical. The alkylidene group (=CR2) of the reagent reacts with the oxygen atom of the carbonyl group to form a hydrocarbon with a double bond, an olefin (alkene). In general:

In investigating reactions involving carbanions, negatively charged organic species, Wittig discovered a class of compounds called ylides mediating a particular type of reaction that became known as Wittig reactions and that proved of great value in the synthesis of numerous organic compounds.

    Extractions: Died: Heidelberg (Germany), 1987 Wittig studied in Tübingen and Marburg. In 1932 he became professor in Braunschweig, in 1937 in Freiburg, in 1944 in Tübingen, in 1956 in Heidelberg. He did research on the stability and the reactions of organic radicals and on the course of those reactions in unsaturated systems. Starting from lithiumphenyl he synthesised ylides. In connection with those investigations he introduced compounds of boron and phosphorous into organic synthesis. In 1979 together with Herbert C. Brown he was awarded the Nobel Prize.

    Extractions: Died: 26 August, 1987 Wittig discovered his versatile route to alkenes via ylide molecules - the Wittig reaction - in 1949. Educated originally at Tübingen, Wittig spent periods at Braunschweig, Freiburg, back to Tübingen again, before taking up the post as director of the organic chemistry department at Heidelberg where he became an emeritus professor in 1967, remaining there until the end of his career. In 1967, he won the Otto Hahn Prize. In 1979, Herbert C. Brown and Georg Wittig were jointly awarded the Nobel Prize: for their development of the use of boron- and phosphorus-containing compounds, respectively, into important reagents in organic synthesis.

Georg Wittig commence ses études de chimie en 1916 à l'université de Tübingen. Après avoir été prisonnier de guerre en Grande-Bretagne, il reprend ses études à l'université de Marburg, où il soutient en 1923 un doctorat préparé sous la direction de K. von Auwers. De 1923 à 1932, il est chef de travaux à l'institut de chimie de l'université de Marburg, puis, de 1932 à 1937, à l'institut technique de Brunswick. Il est ensuite professeur associé à l'université de Fribourg-en-Brisgau. Il est nommé, en 1944, professeur titulaire à Tübingen puis, en 1956, à Heidelberg, où il occupe les fonctions de directeur de l'institut de chimie de l'université. Il prend sa retraite en 1965.
