Abstract
Official abstract text for this publication.
Compounds containing at least one nitrile functional group are produced by hydrocyanation of an organic compound having at least one site of non-conjugated unsaturation, having from 2 to 20 carbon atoms, by reaction with hydrogen cyanide in the presence of a catalytic system containing a complex of nickel having the oxidation state of zero with at least one organophosphorus ligand selected from the group consisting of organophosphites, organophosphonites, organophosphinites and organosphosphines and a cocatalyst of the Lewis acid type of formula: in which M1 and M2 are each elements selected from the group consisting of zinc, boron, aluminum, cadmium, gallium, indium and tin.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for the preparation of a compound containing at least one nitrile functional group, comprising the hydrocyanation of an organic compound having at least one site of non-conjugated unsaturation, having from 5 to 20 carbon atoms, by reaction with hydrogen cyanide in the presence of a catalytic system which comprises a complex of nickel having the oxidation state of zero with at least one organophosphorus ligand selected from the group consisting…
