Prize motivation: "for palladium-catalyzed cross couplings in organic synthesis."
Prize share: 1/3
Nature is full of organic substances - a multitude of chemical compounds that contain the element carbon. Using chemical methods to combine or synthesize organic substances is important in both scientific and industrial contexts. At the mid 1970s, Ei-ichi Negishi began developing chemical reactions in which carbon atoms are bound together so that new compounds are created. The reactions create cross couplings between carbon atoms, with the metal palladium as a catalyst. Palladium facilitates the reaction without becoming incorporated in the final product.
