Abstract
A process for the preparation of alkanedioic acid derivatives comprising reacting an alkenoic acid derivative with carbon monoxide and a nucleophilic compound having a mobile hydrogen atom in the presence of a catalyst system comprising a source of a Group VIII metal, a source of a bidentate diphosphine liquid, a source of an anion and a source of a quinone promoter.

A process for the preparation of alkanedioic acid derivatives which comprises reacting at a temperature in the range of from about 40.degree. C. to about 125.degree. C. and a pressure in the range of from about 2 bar to about 100 bar an alkenoic acid derivative with carbon monoxide and a nucleophilic compound having a mobile hydrogen atom selected from the group consisting of an alcohol, an acid, an amine and water, in the presence of a catalyst system comprising a source of a Group VIII metal, a source of a bidentate phosphine ligand, a source of an anion selected from the group consisting of an acid and a salt of an acid and a quinone promoter.
