Abstract
A carbonylation catalyst system, which comprises: a) a source of a Group VIII metal; b) a source of a phosphine having an aromatic substituent containing an imino nitrogen atom; c) a source of protons; and d) a source of an alkylsulfonate anion, and the use of such a catalyst system in the carbonylation of an acetylenically or olefinically unsaturated compound.
Claims6
A process for the carbonylation of an acetylenically or olefinically unsaturated compound, which comprises reacting an acetylenically or olefinically unsaturated compound with carbon monoxide in the presence of a catalyst system comprising:
- a) a source of a Group VIII metal;
- b) a source of a phosphine having an aromatic substituent containing an imino nitrogen atom;
- c) a source of protons;
- and
- d) a source of an alkylsulphonate anion.
