Ei-ichi Negishi (根岸 英一, Negishi Eiichi) (July 14, 1935 – June 6, 2021) was a Manchurian-born Japanese chemist who was best known for his discovery of the Negishi coupling. He spent most of his career at Purdue University in the United States, where he was the Herbert C. Brown Distinguished Professor and Director of the Negishi-Brown Institute. 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.

Early life and education
Negishi was born in Hsinking (today known as Changchun), the capital of Manchukuo, in July 1935, following the transfer of his father who worked at the South Manchuria Railway in 1936, he moved to Harbin, and lived eight years there. 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.

After obtaining his PhD, Negishi decided to become an academic researcher. Although he was hoping to work at a Japanese university, he could not find a position. 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.
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.
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. Negishi has also reported that organoaluminum compounds and organic zirconium compounds can be used for cross-coupling. He did not seek a patent for this coupling technology and explained his reasoning as follows: "If we did not obtain a patent, we thought that everyone could use our results easily."
In addition, Zr(C5H5)2 obtained by reducing zirconocene dichloride is also called Negishi reagent and is used for the synthesis of polysubstituted benzene.

Personal life and death
Negishi married Sumire Suzuki in 1959 and together they had 2 children.
On the evening of March 12, 2018, both Negishi and his wife were reported missing by family members. Police determined that, based on a purchase made earlier in the day, the couple had left their home in West Lafayette, Indiana, and headed north. At about 5 a.m. the next day, officers in Ogle County, Illinois, received a call asking officers to check on the welfare of an elderly man who was walking on North Route 251, a rural road south of Rockford. When he was taken to hospital, local police found that police in Indiana were looking for the couple. A short time later, Suzuki's body was found on property of the Orchard Hills Landfill in Davis Junction, along with the couple's car.
According to a statement from the family, the couple was trying to get to the Rockford International Airport for a trip when their car became stuck in a ditch on a road near the landfall. Negishi went looking for help and was said to be suffering from an "acute state of confusion and shock." The Ogle County Sheriff’s Department said there was no suspicion of foul play in Suzuki's death, although her cause of death was not released. The family said X was near the end of her battle with Parkinson's disease at the time of her death.
