Born: July 10, 1902, Königshutte Died June 20, 1958. Cologne. German organic chemist. Studied chemistry at the Universities of Berlin and Kiel, receiving his doctorate from the latter in 1926. Professor at Kiel University (1934-36). Head of research at E.G. Farben Industries (36-40). Professor of chemistry and head of the chemical research laboratory at the University of Cologne (40). In 1928, together with his mentor O. Diels, he discovered the reaction between dienes and quinones. He also discovered that dienes react easily with various compounds containing activated double or triple bonds (diene synthesis), which is now known as the Diels-Alder reaction. He was the first to experimentally elucidate the nature of this reaction, and demonstrated that it could be applied to the synthesis of many cyclic compounds. He also used this reaction to develop synthetic resins. For these achievements, he and Diels were awarded the Nobel Prize in Chemistry in 1950.

[生]1902.7.10. ケーニヒスヒュッテ [没]1958.6.20. ケルン ドイツの有機化学者。ベルリン大学とキール大学で化学を修め,1926年キール大学で学位取得。キール大学教授 (1934~36) 。イー・ゲー・ファルベン工業の研究部長 (36~40) 。ケルン大学の化学教授兼化学研究所部長 (40) 。 28年に師 O.ディールスとともに,ジエンとキノンの反応を発見。ジエンが,活性化された二重または三重結合をもつ種々な化合物と容易に反応すること (ジエン合成) を発見。これは現在ディールス=アルダー反応と呼ばれている。この反応により反応の性質を最初に実験的に解明し,多くの環状化合物の合成に応用できることを示した。さらに,この反応を使って合成樹脂を開発した。これらの業績により,50年ディールスとともにノーベル化学賞を受賞した。 出典 ブリタニカ国際大百科事典 小項目事典ブリタニカ国際大百科事典 小項目事典について 情報 |
