The invention relates to phosphacyclohexanes of general formulae I and II, wherein the following designations, among others, apply: R can represent hydrogen, C1-100-alkyl, C7-20-aralkyl, C7-20-alkaryl, and C6-12-aryl: R1 to R10 can independently represent hydrogen, C1-20-alkyl, C7-20-aralkyl, C7-20-alkaryl, and C6-12-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.
该发明涉及一般式I和II的磷环己烷化合物,其中包括以下标记:R可以代表氢、C1-100-烷基、C7-20-芳基烷基、C7-20-烷基芳基和C6-12-芳基;R1至R10可以独立代表氢、C1-20-烷基、C7-20-芳基烷基、C7-20-烷基芳基和C6-12-芳基;W、W′可以独立代表含有1至20个碳原子的单键或桥连接,可形成环或芳香族基,并且可以被杂原子打断。所述磷环己烷化合物被用作过渡金属络合物中的配体,所述过渡金属属于周期表第VIII至X族。
