ABSTRACT:
Improved liquid phase process useful in the hydrocyanation of diolefinic compounds to produce nonconjugated acyclic nitrites and to the liquid phase process of isomerization of the nitrites to 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. The invention also provides a novel method of making phosphorochloridite.
