Early life and education

Kochi was born to Japanese immigrant parents on May 17, 1927, in Los Angeles, California, where he and his family had lived until he and his family were imprisoned at the Gila River War Relocation Center in 1942 just after the United States entered the Second World War and

Research

Kochi's research examined the interactions of electron donors and acceptors. One topic of his study was the nitration of benzene to give

, including the discovery of Cu, Fe, and Ag-catalyzed cross-coupling processes (which preceded the discovery of the better known Pd and Ni-catalyzed versions), as well as several metal-catalyzed oxidative processes.

catalysis sparked significant efforts to further develop cross-coupling reactions catalyzed by metals such as Fe in particular. His research in organometallic chemistry emphasized the importance of electron-transfer processes and radical species as intermediates. Many of these results (and the results of other investigators) are summarized in a monograph.


Awards and honors
