The racemic title compound, [FePdCl2(C5H5)(C36H29P2)]·2(CH3)2SO, features a Pd-chelating 1,3-diphosphine, which is substituted at a P-bearing asymmetric C atom by a ferrocenyl group. The PdII atom is in a distorted quadratic coordination by two P an

Novel enantiopure ferrocene-based aminophosphine and diphosphine ligands for asymmetric catalysts have been developed. In all cases a highly flexible synthetic approach allowed access to ligands with different ferrocenyl backbones and with a variety

Negishi coupling conditions were identified that allowed the synthesis of unsymmetrically 2,2″-disubstituted biferrocenes from non-identical ferrocene fragments. The coupling reaction of (R)-1-(N,N-dimethylamino)ethylferrocene (1) with enantiopure
