Ei-ichi Negishi (根岸 英一, Negishi Eiichi, born July 14, 1935)[2] is a Manchurian-born Japanese chemist who has spent most of his career at Purdue University in the United States. He is the Herbert C. Brown Distinguished Professor and Director of the Negishi-Brown Institute at Purdue.[3] He is best known for his discovery of the Negishi coupling.[4] He was awarded the 2010 Nobel Prize in Chemistry "for palladium catalyzed cross couplings in organic synthesis" jointly with Richard F. Heck and Akira Suzuki.[5]

Early life and education

Negishi was born in Hsinking, the capital of Manchukuo (now Changchun, China) 1935,[6] following the transfer of his father who worked at the South Manchuria Railway in 1936, he moved to Harbin, and lived eight years there.[7] In 1943, when he was nine, the Negishi family moved to Incheon, and a year later to Kyongsong Prefecture (now Seoul), both in Japanese-occupied Korea. In November 1945, three months after World War II ended, they moved to Japan. Negishi graduated from the University of Tokyo in 1958 and did his internship at Teijin. He went on to study in the United States and obtained his PhD from the University of Pennsylvania in 1963, under the supervision of professor Allan R. Day.

Career

Peter Diamond, Dale T. Mortensen, Christopher A. Pissarides, Konstantin Novoselov, Andre Geim, Akira Suzuki, Ei-ichi Negishi, and Richard Heck, Nobel Prize Laureates 2010, at a press conference at the Royal Swedish Academy of Sciences in Stockholm.

After obtaining his PhD, Negishi decided to become an academic researcher.[8] Although he was hoping to work at a Japanese university, he could not find a position.[9] In 1966 he resigned from Teijin, and became a postdoctoral associate at Purdue University, working under future Nobel laureate Herbert C. Brown. From 1968-1972 he was an instructor at Purdue.[10]

In 1972, he became an assistant professor at Syracuse University, where he was promoted to associate professor in 1979, before returning to Purdue University as a full professor in the same year.[10]

He discovered Negishi coupling, a process which condenses organic zinc compounds and organic halides under a palladium or nickel catalyst to obtain a C-C bonded product. For this achievement, he was awarded the Nobel Prize in Chemistry in 2010.[11] Negishi has also reported that organoaluminum compounds and organic zirconium compounds can be used for cross-coupling. He has not obtained a patent for this coupling technology, his reasoning being as follows: "If we did not obtain a patent, we thought that everyone could use our results easily."[12] In addition, Zr(C5H5)2 obtained by reducing zirconocene dichloride is also called Negishi reagent and is used for the synthesis of polysubstituted benzene.

Honors

His disappearance and the death of his wife

The evening of March 12, 2018, Negishi and his wife, 80-year old Sumire Negishi, were reported missing, along with their car. The next afternoon deputies of the Ogle County, Illinois Sheriff’s office found Ei-ichi Negishi, 82, walking in a daze near the Orchard Hills Landfill, outside Rockford. Shortly thereafter they found the body of his wife, along with the couple's car, on a perimeter road.[17] The pair had been driving to Rockford International Airport when he apparently lost the way.[18] Foul play is not suspected.[19] Purdue University president and former Indiana governor Mitch Daniels lamented the death of Sumire Negishi, stating: "Throughout a lifetime of love and loyalty, she supported her husband in a career of tremendous contributions to science and to the teaching and training of subsequent generations of top scientists. It appears that the Parkinson’s disease from which she has been suffering and the mental confusion that age can bring to the most brilliant minds combined to produce the recent tragic events. That these phenomena are so common does not make their consequences any less cruel."[19]
