The invention relates to phosphacyclohexanes of general formulae I and II, wherein the following designations, among others, apply: R can represent hydrogen, C 1-100 -alkyl, C 7-20 -aralkyl, C 7-20 -alkaryl, and C 6-12 -aryl: R 1 to R 10 can independently represent hydrogen, C 1-20 -alkyl, C 7-20 -aralkyl, C 7-20 -alkaryl, and C 6-12 -aryl: W, W′ can independently represent single bonds or bridges comprising 1 to 20 carbon atoms, which can form part of a cyclic or aromatic group and can be interrupted by heteroatoms. Said phosphacyclohexanes are used as ligands in transition metal complexes of transition metals belonging to groups VIII to X of the periodic table. |
