  • Title: Asymmetric transfer hydrogenation of ketimines using well-defined iron(II)-based precatalysts containing a PNNP ligand.
    Author: Mikhailine AA, Maishan MI, Morris RH.
    Journal: Org Lett; 2012 Sep 07; 14(17):4638-41. PubMed ID: 22924839.
    Abstract:
    Well-defined iron(II)-based complexes containing PNNP ligands catalyze a highly enantioselective reduction of N-(diphenylphosphinoyl)- and N-(p-tolylsulphonyl)-ketimines. Under mild conditions and low catalyst loading, the ketimines are successfully reduced to the corresponding amines in enantiomeric excess ranging from 94 to 99%.
