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.
