Rhodium(I)-catalysed asymmetric hydrosilylation of ketones using new diferrocenyl dichalcogenides (R,S)-{[EC5H3CHMe(NMe2)]Fe(C5H5)}2(E = S, Se, Te), as chiral ligands

The new chiral compounds, (R,S)-di[2-(1-dimethylaminoethyl)ferrocenyl] dichalcogenides (R,S)-{[EC5H3CHMe(NMe2)]Fe(C5H5)}2(E = S, Se, Te), work effectively as chiral ligands for the rhodium(I)-catalysed asymmetric hydrosilylation of alkyl aryl ketones resulting in high enantiomeric excess and moderate chemical yields.
