Synthesis of highly enantiomerically enriched planar chiral ruthenium complexes via Pd-catalysed asymmetric hydrogenolysis.

ABSTRACT

Key elements in this communication are a very efficient microwave synthesis of [RuCp(naphthalene)][PF(6)], the precursor of [RuCp(CH(3)CN)(3)][PF(6)], and a Pd-catalysed asymmetric hydrogenolysis to afford planar chiral ruthenium complexes with high levels of enantioselectivity using a bulky chiral phosphoramidite ligand.
