The absolute configurations of three new enantiomerically pure ferrocenylphosphole compounds, namely (2S,4S,SFc)-4-methoxymethyl-2- [2-(9-thioxo-9λ5-phosphafluoren-9-yl)ferrocenyl]-1,3-dioxane, [Fe(C5H5)(C23H22O3PS)], (III), (SFc)-[2-(9-thioxo-9λ5-phosphafluoren-9-yl) ferrocenyl]methanol, [Fe(C5H5)(C18H 14OPS)], (V), and (SFc)-diphenyl[2-(9-thioxo- 9λ5-phosphafluoren-9-yl]ferrocenylmethyl]phosphine, [Fe(C 5H5)(C30H23P2)], (VIII), have been unambiguously established. All three ligands contain a planar chiral ferrocene group, bearing a dibenzophosphole and either a dioxane, a methanol or a diphenylphosphinomethane group on the same cyclopentadienyl. In compound (V), the occurrence of O - H...S and C - H...S hydrogen bonds results in the formation of a two-dimensional network parallel to (001). The geometry of the ferrocene frameworks agrees with related reported structures.

A convenient synthesis of new chiral ferrocenene-bridged phosphole-phosphane ligands in an enantiomerically pure form has been developed. These new chiral P,P ligands have been tested in a palladium-catalysed allylic substitution reaction. High activities and moderate enantioselectivities (up to 61 %) were observed. A palladium(II) complex has been isolated and its crystal structure established. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
