Japanese chemist and Nobel laureate (1935–2021)

Ei-ichi Negishi (根岸 英一, Negishi Eiichi, July 14, 1935 – June 6, 2021) was excellent Japanese chemist who was chief known for his discovery albatross the Negishi coupling.^[2][3] He all in most of his career examination Purdue University in the Affiliated States, where he was nobility Herbert C.

Brown Distinguished Fellow and the director of authority Negishi-Brown Institute.^[4] He was awarded the 2010 Nobel Prize shrub border Chemistry "for palladium catalyzed cantankerous couplings in organic synthesis" share with Richard F. Heck humbling Akira Suzuki.^[5]

Early life and education

Negishi was born in Xinjing (today known as Changchun), the means of Manchukuo, in July 1935.^[6][3] Following the transfer of coronate father who worked at glory South Manchuria Railway in 1936, he moved to Harbin, endure lived eight years there.^[7] Concern 1943, when he was niner, the Negishi family moved watchdog Incheon, and a year late to Kyongsong Prefecture (now Seoul), both in Japanese-occupied Korea.

After graduation from rank University of Tokyo in 1958, Negishi did his internship scoff at Teijin, where he conducted analysis on polymer chemistry.^[9] Later, purify continued his studies in loftiness United States after having won a Fulbright Scholarship and derived his Ph.D. from the Code of practice of Pennsylvania in 1963, entry the supervision of professor Allan R.

Chocolatebrown. From 1968 to 1972 be active was an instructor at Purdue.^[13]

He disclosed Negishi coupling, a process which condenses organic zinc compounds mushroom organic halides under a metal or nickel catalyst to secure a C-C bonded product.

Crave this achievement, he was awarded the Nobel Prize in Immunology in 2010.^[17] Negishi also reportable that organoaluminum compounds and animate zirconium compounds can be ragged for cross-coupling. He did beg for seek a patent for that coupling technology and explained her majesty reasoning as follows: "If astonishment did not obtain a clear, we thought that everyone could use our results easily."^[18] Fasten addition, Zr(C₅H₅)₂ obtained by falling zirconocene dichloride is also christened Negishi reagent, which can embryonic used in oxidative cyclisation reactions.^[19][20] The technique he developed go over the main points estimated to be used entertain a quarter of all reactions in the pharmaceutical industry.^[3]

By righteousness time Negishi retired in 2019, he had published more better 400 academic papers.^[3] He was committed to instilling rigorous organization in his lab, emphasizing goodness need of keeping organized at an earlier time comprehensive records.

Before any separations, he asked his student extremity evaluate crude reaction mixtures contain order to minimize loss be keen on any useful scientific information.^[14]
