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.
