Enantioselective nickel catalyzed butadiene hydroalkoxylation with ethanol: from experimental results to kinetics parameters
Résumé
The enantioselective hydroalkoxylation of butadiene with ethanol has been performed in the presence of nickel-based catalysts and chiral diphosphine ligands. Ee’s up to 77% could be obtained from the use of atropoisomeric chiral ligands such as Segphos. The kinetics parameters of the reaction were determined using a qualitative kinetic model to better explain the l/b isomerization and racemization processes observed for long reaction times.
