Carbonylation process of the ethylenically unsaturated compound , catalyst system incorporating a novel carbonylation ligand and such ligands .

摘要

Bidentate ligand novel catalysts of the general formula (I) are described. Represents a hydrocarbyl aromatic structure having at least one aromatic ring, in the aromatic ring, R, via the linking group each on adjacent atoms of the available aromatic ring of the at least one, if present ^{Q 1} and ^{Q 2} are bonded to each other. Represents a group bonded to the atom Q ¹ each via a tertiary carbon atom, and X ² groups X ^1, X ⁴ and groups X ³ are each atom via a substituted aromatic ring carbon atom or a primary I represent a group that is bonded to Q ^2. A and B, represents a lower alkylene linking group optional.^{Q 1} and ^{Q 2} represents phosphorus, arsenic or antimony. Also, a source of hydroxyl groups, a source of anion, and is obtained by mixing a compound thereof Group 8, or 9 or 10 metal group, a bidentate ligand of the general formula (I) optionally in the presence of a catalyst system capable comprising a step of reacting carbon monoxide and a compound, carbonylation process of the ethylenically unsaturated compounds are described.
