ABSTRACT:
Process for the hydroformylation of an optionally substituted ethylenically unsaturated compound by reaction thereof with carbon monoxide and hydrogen in the presence of a specific catalyst system which includes a source of Group VIII metal cations; a diphosphine ligand having the general formula (I):in-line-formulae description="In-line Formulae" end="lead"?X1—R—X2  (I)in-line-formulae description="In-line Formulae" end="tail"?wherein X1and X2each independently represent an optionally substituted cyclic group with at least 5 ring atoms, of which one is a phosphorus atom, and R represents a bivalent optionally substituted bridging group which is connected to each phosphorus atom by a sp2hybridized carbon atom; an acid having a pKa<3; and a source of halide anions.
