HYDROFORMYLIERUNGS VERFAHREN

摘要

Process for the hydroformylation of ethylenically unsaturated compounds, by reaction with carbon monoxide and hydrogen in the presence of a catalyst based on a metal of the platinum group, a source of anions other than halide anions and a bidentate ligand of the formula R<1>R<2>M<1>RM<2>R<3>R<4> wherein M<1> and M<2> are phosphorus, arsenic or antimony, R is a bivalent organic bridging group with 1 to 4 atoms in the bridge, R<1> and R<2> together represent a bivalent cyclic group and R<3> and R<4> independently represent an optionally substituted hydrocarbyl group or together represent a bivalent substituted or non-substituted cyclic group whereby the two free valencies are linked to M<2>.
