Abstract
Described herein is a process for the hydrocyanation of diolefins by employing a catalyst comprising the combination of a zero-valent nickel compound and certain bidentate phosphorus compounds, and a process for isomerizing 2-alkyl-3-monoalkenenitrile to form linear nitriles by the use of such catalyst.
