The absolute configurations of three new enanti-omerically pure ferrocenylphosphole compounds, namely (2S,4S,S-Fc)-4-methoxy-methyl-2-[2-(9-thioxo-9 lambda(5)-phosphafluoren-9-yl)-ferro-cenyl]-1,3-dioxane, [Fe(C5H5)(C23H22O3PS)], (III), (S-Fc)-[2-(9-thioxo-9 lambda(5)-phosphafluoren-9-yl)ferrocenyl]methanol, [Fe(C5H5)(C18H14OPS)], (V), and (S-Fc)-diphenyl[2-(9-thioxo-9 lambda(5)-phosphafluoren-9-yl]ferrocenylmethyl]phosphine, [Fe(C5H5)(C30H23P2)], (VIII), have been unambiguously established. All three ligands contain a planar chiral ferrocene group, bearing a dibenzo-phos-phole and either a dioxane, a methanol or a diphenyl-phosphino-methane group on the same cyclopentadienyl. In compound (V), the occurrence of O-H center dot center dot center dot S and C-H center dot center dot center dot 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.
