Chemistry Nobel laureate Ei-ichi Negishi dies at 85

Ei-ichi Negishi, who shared the 2010 chemistry Nobel prize with Richard Heck and Akira Suzuki for a palladium-catalysed cross coupling technique to link carbon atoms and synthesise molecules, has died at the age 85. Known for his discovery of the Negishi coupling, an important reaction that forms carbon–carbon bonds, he had been a professor in the chemistry department at Purdue University in the US since 1979 and served in a distinguished post since 1998. His 6 June passing came only two days after the death of Swiss physical chemist Richard Ernst, who received the 1991 chemistry Nobel prize.
