3. 2. Asymmetric Hydrogenations using N, P - Ligated Iridium Complexes

   Författare :Alexander Paptchikhine; Pher G. Andersson; Karl Anker Jørgensen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; asymmetric hydrogenation; iridium; birch; boronates; fluorine;

   Sammanfattning : The research described in this thesis focuses on the catalytic asymmetric hydrogenation of prochiral olefins using N, P – chelated iridium catalysts. This catalytic system is tolerant to a wide range of substrates and performs better than the well-known ruthenium- and rhodium-catalytic systems for substrates devoid of coordinating groups in proximity of the olefin.
