VERFAHREN ZUR HYDROFORMYLIERUNG VON ETHYLENISCH UNGESÄTTIGTEN VERBINDUNGEN MITTELS EINER ZWEIZÄHNIGEN DIPHOSPHIN-ZUSAMMENSETZUNG MIT EINER VERBRÜCKENDEN GRUPPE ENTHALTEND SP2-HYBRIDISIERTE UND AN DIE PHOSPHORATOME GEBUNDENE KOHLENSTOFFATOME |
摘要 |
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"?>X<SUP>1</SUP>-R-X<SUP>2</SUP> (I)<?in-line-formulae description="In-line Formulae" end="tail"?> wherein X<SUP>1 </SUP>and X<SUP>2 </SUP>each 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 sp<SUP>2 </SUP>hybridized carbon atom; an acid having a pK<SUB>a</SUB><3; and a source of halide anions. |
