Curriculum Vitae:
Prof. Bäckvall is a Member of the Royal Swedish Academy of Sciences, Finnish Academy of Science and Letters, and Academia European. In 2008-2016, he was a member of the Nobel Committee for Chemistry. He is a member of a number of Editorial Boards for scientific journals.
Prof. Bäckvall is renowned for his contribution to organopalladium chemistry and catalytic oxidation reactions where he has done mechanistic work and developed new reactions. He has also pioneered the development of efficient systems for dynamic kinetic resolution of alcohols and amines based on combined metal and enzyme catalysis. More recently the enantioselectivity of enzymes was improved by directed evolution. The Bäckvall group has also developed a variety of useful aerobic biomimetic oxidation reactions. In these reactions electron-transfer mediators are employed to facilitate low-energy electron transfer similar to that occurring in natural systems. Recent applications of the latter topic involve palladium-catalyzed oxidative carbocyclizations. He has published more than 500 papers and given more than 175 plenary and main lectures at international conferences.
