ABSTRACT:
Improved liquid phase process useful in the hydrocyanation of diolefinic compounds to produce nonconjugated acyclic nitriles and to the liquid phase process of isomerization of the nitrites to, among other things, 3- and/or 4-monoalkene linear nitriles. The improvement involves conducting the process in the presence of zero-valent nickel and a multidentate phosphite ligand. Novel multidentate phosphite ligands and catalyst precursor compositions made therefrom are also disclosed.
