Nobel Prize in Chemistry Awarded to Ei-ichi Negishi, Gr&#;63
Ei-ichi Negishi, the Herbert C. Brown Distinguished Professor of Chemistry at Purdue University and a Penn Chemistry Ph.D., has won the Nobel Prize in Chemistry, along with Richard Heck (University of Delaware) and Akira Suzuki (Hokkaido University, Sapporo, Japan). The three scientists were recognized by the Royal Swedish Academy of Sciences in Stockholm for having independently made advances in using the palladium complexes as catalysts to link together carbon molecules into larger, more complicated structures. As noted by the Nobel Prize committee, "Palladium-catalyzed cross coupling is used in research worldwide, as well as in the commercial production of pharmaceuticals and molecules used in the electronics industry."
Negishi did his dissertation work under Professor of Chemistry Allan Day while at Penn. He is now the seventh Nobel laureate to be associated with the Penn Chemistry Department. The previous laureates include the following:
Christian B. Anfinsen, who received an M.S. in Chemistry at Penn in Anfinsen was the recipient of the Nobel Prize in Chemistry for his work in establishing the connection bet
Thieme Chemistry mourns the loss of Professor Ei-ichi Negishi
Eminent chemist and Science of Synthesis author Ei-ichi Negishi passed away on June 6th,
Thieme Chemistry were sad to learn of the death of Prof. Ei-Ichi Negishi, who passed away on June 6th at the age of Prof. Negishi, who spent the majority of his career at Purdue University (Indiana, USA), was a joint recipient of the Nobel Prize in Chemistry for his work on “palladium-catalyzed cross couplings in organic synthesis”. In particular, Prof. Negishi is notable for his development of the Negishi reaction, where organozinc compounds are coupled with organic halides and triflates under palladium catalysis.
Prof. Negishi authored several chapters for Science of Synthesis, focused on the organometallic chemistry and the carbon–carbon bond forming processes that he was notable for developing. Further details of his Science of Synthesis contributions can be found here.
He will be dearly missed, and our sincere condolences go to his family, friends, and colleagues.

Nobel Research
Professor Ei-ichi Negishi was a pioneer in developing metal-based reactions called palladium-catalyzed cross-coupling, that allow for easy and efficient synthesis of complex organic compounds.
By creating a more precise method for coupling two different (or same) carbon groups, Dr. Negishi created a powerful tool for synthesizing a wide range of useful chemicals used in medicine, agriculture, and electronics.
He shared the Nobel Prize with Richard Heck of the University of Delaware and Akira Suzuki from Hokkaido University in Sapporo, Japan. (Both Negishi and Suzuki studied at Purdue under Professor Herbert C. Brown, a Nobel Laureate.)
Their methods are now widely used in industry and research in a variety of applications including: pharmaceutical antibiotics that work on drug resistant bacteria, agricultural chemicals that protect crops from fungi, and electronic light-emitting diodes used in the production of extremely thin monitors.

Ei-ichi Negishi () was the Herbert C. Brown Distinguished Professor in the Department of Chemistry at Purdue. He came to Purdue in as a postdoctoral researcher in the lab of the Late Herbert C. Brown, and published 33 papers with Prof. Brown up through the time that Prof. Brown was awarded the Nobel Prize in Chemistry in With the award of the Nobel to Ei-ichi Negishi in , Purdue has the rare distinction of a pair of Nobel Prize awards in two closely related areas. Professor Negishi’s Nobel Prize was awarded in recognition of his work on palladium-catalyzed cross-coupling chemistry (known world-– wide as the Negishi coupling). That work was described by the Nobel Foundation as "great art in a test tube". This is certainly appropriate as great scientists regard themselves as artists and explorers. The impact of that work was widespread, as it had been used in synthetic organic chemistry research worldwide, as well as in the commercial production of an array of pharmaceuticals and molecules used in the electronics industry.
