From 1963 until 1965, Suzuki worked as a postdoctoral student with
Herbert C. Brown at
Purdue University and after returning to the Hokudai he became a full professor there. The postdoctoral experience was utilized in the study of the
coupling reaction with his assistant
Norio Miyaura and led to the discovery of
Suzuki reaction announced in 1979. Its organic
boronic acids with
aryl and
vinyl group are stable to water and air, easy to handle, and because the conditions required for use are also relatively mild, even among the several cross-coupling techniques, it is said to be easy to use. Its full mechanism is shown in the image below. With his retirement from Hokudai in 1994 he took several positions in other universities: 1994–1995
Okayama University of Science and 1995–2002
Kurashiki University of Science and the Arts. In addition, he was an invited professor at Purdue University (2001),
Academic Sinica and the
National Taiwan University (2002). In 2010, Suzuki was jointly awarded the
Nobel Prize for Chemistry together with
Richard F. Heck and
Ei-ichi Negishi. To celebrate International Year of Chemistry (IYC 2011), Suzuki was interviewed by the
UNESCO Courier magazine, he said: Today some people see chemistry just as a polluting industry, but that is a mistake ... Without it, productivity would drop and we could not enjoy the life we know today. If there is pollution, it is because we are releasing harmful substances. Obviously, we have to adapt treatment and management regimes and work to develop chemical substances and manufacturing processes that respect the environment. In 2014, a Canadian-Chinese student asked for Suzuki's advice: "how can I become a great chemist like you?", Suzuki answered him: "... above all else, you must learn to see through the appearance to perceive the essence." ==Invention without patent==
