摘要： The invention provides a process for the carbonylation of ethylenically unsaturated compounds by reaction with carbon monoxide and a co-reactant in the presence of a substantially non-acidic catalyst system based on a palladium compound and a bidentate ligand of the formula (I): R R M RM R R wherein M and M independently represent a phosphorus, arsenic or antimony atom, R represents a bivalent organic bridging group, R , R , R and R independently represent substituted or non-substituted aliphatic groups, with the proviso that R together with R , and/or R together with R represent a bivalent cyclic group with at least 5 ring atoms whereby the two free valencies are linked to M or M , respectively. In addition, the invention provides catalytic compositions comprising: a) a palladium compound; b) a bidentate ligand of the formula (II): R R PRPR R wherein R is a bivalent organic bridging group containing from 1 to 10 atoms in the bridge and R , R , R and R independently represented substituted or non-substituted aliphatic groups, with the proviso that R together with R and/or R together with R represent a bivalent cyclic group with at least 6 ring atoms whereby the two free valencies are linked to the phosphorus atoms(s) and c) a basic compound.
