摘要：Process for the hydroformylation of an optionally substituted ethylenicallyunsaturated compound by reaction thereof with carbon monoxide and hydrogen in thepresence of a specific catalyst system. The specific catalyst system comprises: a) a sourceof group VIII metal cations; b) a diphosphine ligand having the general formula X1-R-X2,wherein X1 and X2 each independently represent an optionally substituted cyclic groupwith at least 5 ring atoms, of which one is a phosphorus atom, and R represents a bivalentoptionally substituted bridging group, connected to each phosphorus atom by a sp2hybridized carbon atom; c) an acid having a pKa < 3, measured in an aqueous solution at18 °C or a salt derived thereof; and d) a source of halide anions. Furthermore somespecific bidentate diphosphines used in this process are described.
