Cobalt(II) Catalyzed Asymmetric Hydrovinylation of Alkyl- and Trialkylsilyloxy-1,3-Dienes
… with aryl alkenes and 1,3-dienes. The hydrovinylation reaction, the formal addition of a hydrogen atom and an alkene across a pi-system, is an atom economical reaction that allows for the synthesis of value-added products from simple commodity chemicals and feedstock gases. The true …

Synthesis and application of chiral phosphorous triamide ligands
… of 63% was attained in the Ni catalysed hydrovinylation of styrene at relatively high reaction temperature. The results of this thesis demonstrate that chiral PTAs are accessible and can provide significant levels of enantioselectivity in asymmetric catalysis. Their steric and electronic …

Chirale Phosphortriamide und Phosphin-Phosphoramidite als Liganden für die asymmetrische Katalyse
… excess obtained was 48% for Ni-catalysed hydrovinylation of styrene. The phosphine-phosphoramidites were especially tested as ligands for asymmetric hydrogenation employing Rhodium or Iridium as the catalytically active metal. In the Rh-catalysed hydrogenation of functionalised olefins …
