Multidentate phosphite ligands are disclosed for use in reactions such as hydrocyanation and isomerization. The catalyst compositions made therefrom and the various catalytic processes which employ such multidentate phosphite ligands are also disclosed. In particular, the ligands have heteroatom-containing substituents on the carbon attached to the ortho position of the terminal phenol group.
多齿磷酸酯配体被用于反应,如氢氰化和异构化。由此制成的催化剂组合物以及采用这些多齿磷酸酯配体的各种催化过程也被披露。特别是,这些配体在连接到末端酚基的邻位碳上具有含杂原子的取代基。
