John Michael Brown
John Michael Brown (* 1939 ) is a British chemist ( organic chemistry ). He is a professor at Oxford University .
Brown studied at the University of Manchester , where he received his PhD with Arthur John Birch , and was a post-doctoral student at Columbia University with Ronald Breslow . He taught at the University of Warwick from 1966 to 1974 and was a lecturer in organic chemistry at Oxford from 1974 to 2008 , where he is a Fellow of Wadham College and has since retired. At Oxford he introduced modern organometallic catalysis in the 1970s.
He deals with enantioselective synthesis in organic chemistry and was involved in the development of transfer hydrogenation with rhodium and the clarification of its mechanisms (reactive intermediates, Halpern-Brown mechanism). He dealt with stereo control in targeted hydrogenation and asymmetric hydroboration , where he and his research group introduced the ligand Quinap. He investigated palladium-catalyzed reactions ( Heck reaction ) of alkenes as well as palladium-catalyzed methylation with an internally activated TMS group, the Soai reaction and reactions with ruthenium catalyst.
In 2013 he received the Robert Robinson Award . He is a Fellow of the Royal Society .
