ABSTRACT:
The present invention provides a process for hydrocyanation comprising reacting a nonconjugated, ethylenically unsaturated compound in a two phase process solvent with HCN in the presence of a Lewis acid promoter and a catalyst system comprising zero-valent nickel and an organic phosphorous containing ligand having the structure (PR.sub.2).sub.n R' where n is an integer from 1 to 2, R and R' are organic residues which may be the same or different and where the R or R' contain at least one C9 to C40 aliphatic group positioned as a tail extending away from the primary ligand structure rendering the ligand lipophilic.
